calculate the number of moles equivalent to 25.0 gram of copper II sulfate pentahydrate [CuSO4 5H2O]​

Answers

Answer:

The answer is 0.1 mol

Explanation:

To calculate the number of moles in the given substance we use the equation

[tex]n = \frac{m}{M} [/tex]

where

n is the number of moles

M is the molar mass

m is the mass of the substance

To calculate the number of moles we must first find the molar mass

That's

M( CuSO4 5H2O )

Cu = 64 , S = 32 , O = 16 H = 1

So we have

M( CuSO4 5H2O ) = 64 + 32 + (16 × 4) +

5( 2 + 16)

M( CuSO4 5H2O ) = 96 + 64 + 5(18)

M( CuSO4 5H2O ) = 160 + 90

M( CuSO4 5H2O ) = 250 g/mol

M( CuSO4 5H2O ) = 250 g/mol

mass of CuSO4 5H2O = 25 g

Substitute the values into the above formula

That's

[tex]n = \frac{25g}{250 \: g/mol} [/tex]

We have the final answer as

n = 0.1 mol

Solution:

Atomic weight of Elements:

Cu = 64S = 32O = 16H = 1

❍ Molecular weight of [tex]\sf{CuSO_4.5H_2O}[/tex]

The lock-and-key mechanism refers to
the complementary shapes of an enzyme and a substrate.
the attractive forces between an enzyme and a substrate.
the ability of an enzyme to lower the activation energy of a reaction.
the ability of an enzyme to "unlock" the products of a reaction.

Answers

Answer:

A). The complementary shapes of an enzyme and a substrate.

Explanation:

The Lock-and-key mechanism was proposed by Emil Fischer for the first time and characterized as the metaphor which helps in elucidating the specificity of the enzymatic reactions. In this metaphor, the lock is described as the enzyme while 'key' is characterized as the substrate which the enzyme acts upon. If the key is not appropriately sized, it will not fit into the active site i.e. the keyhole of the lock or enzyme and reaction will not take place. Thus, option A is the correct answer.

Suppose 300 mL of 0.50 M lithium bromide solution and 300 mL of 0.70 M rubidium bromide solution are combined. What is the concentration of the bromide ion in the resulting solution?

Answers

Answer:

0.60 mol·L⁻¹  

Explanation:

Data:  

LiBr: c = 0.50 mol/L; V =300 mL

RbBr: c = 0.70 mol/L; V =300 mL

1. Calculate the moles of Br⁻ in each solution

(a) LiBr

[tex]\text{Moles} = \text{0.300 L} \times \dfrac{\text{0.50 mol}}{\text{1 L}} = \text{ 0.150 mol}[/tex]

(b) RbBr

[tex]\text{Moles} = \text{0.300 L} \times \dfrac{\text{0.70 mol}}{\text{1 L}} = \text{ 0.210 mol}[/tex]

2. Calculate the molar concentration of Br⁻

(a) Moles of Br⁻

n = 0.150 mol  + 0.210 mol = 0.360 mol

(b) Volume of solution

V = 300 mL + 300 mL = 600 mL = 0.600 L

(c) Molar concentration

[tex]c = \dfrac{\text{moles}}{\text{litres}} = \dfrac{\text{0.360 mol}}{\text{0.600 L}} = \textbf{0.60 mol/L}[/tex]

 

The concentration of Br ions in the resulting solution of LiBr and RbBr has been 0.6 M.

The addition of LiBr and RbBr has been dissociated into the equal moles of Li, Rb, and Br.

[tex]\rm LiBr\;\rightarrow\;Li^+\;+\;Br^-[/tex]

[tex]\rm RbBr\;\rightarrow\;Rb^+\;+\;Br^-[/tex]

Thus 1 mole of LiBr = 1 mole Br

1 mole RbBr = 1 mole Br.

The moles of LiBr in 0.5 M solution:

Molarity = [tex]\rm moles\;\times\;\dfrac{1000}{volume\;(ml)}[/tex]

0.5 = [tex]\rm moles\;\times\;\dfrac{1000}{300\;ml}[/tex]

Moles of LiBr = 0.15 mol

The moles of Br from LiBr = 0.15 mol.

The moles of RbBr in 0.7 M solution:

Molarity = [tex]\rm moles\;\times\;\dfrac{1000}{volume\;(ml)}[/tex]

0.7 = [tex]\rm moles\;\times\;\dfrac{1000}{300\;ml}[/tex]

Moles of RbBr = 0.21 mol

The moles of Br from RbBr = 0.21 mol.

The total moles of Br ions from LiBr and RbBr has been :

= 0.15 + 0.21

= 0.36 mol.

The total volume of the solution will be:

= 300 + 300 ml

= 600 ml.

The concentration of the Br ion has been:

Molarity = [tex]\rm moles\;\times\;\dfrac{1000}{volume\;(ml)}[/tex]

Molarity of Br ions =  [tex]\rm 0.36\;\times\;\dfrac{1000}{600\;ml}[/tex]

Molarity of Br ions = 0.6 M.

The concentration of Br ions in the resulting solution of LiBr and RbBr has been 0.6 M.

For solving this question, We need to know how to find moles of solution or any substance if a certain weight is given.

[tex] \boxed{ \sf{No. \: of \: moles = \frac{Given \: weight}{Molecular \: weight} }}[/tex]

Solution:

Atomic weight of elements:

Ca = 40P = 31O = 16

❍ Molecular weight of [tex]\sf{Ca_3(PO_4)_2}[/tex]

= 3 × 40 + 2 × 31 + 8 × 16

= 120 + 62 + 128

= 310 g/mol

❍ Given weight: 20 g

Then, no. of moles,

⇛ No. of moles = 20 g / 310 g mol‐¹

⇛ No. of moles = 0.0645 moles

⚘ No. of moles of Calcium phospate in the given weight = 0.0645 moles.

━━━━━━━━━━━━━━━━━━━━

Answer:

The answer is 0.08mol

Explanation:

To find the number of moles in calcium phosphate we use the formula

[tex]n \: = \frac{m}{M} [/tex]

where

n is the number of moles

M is the molar mass

m is the mass of the substance

To find the number of moles we must first find the molar mass

Chemical formula for calcium phosphate is

Ca3( PO4)2

Ca = 40 , P = 31 , O = 16

So the Molar mass of calcium phosphate is

M( Ca3( PO4)2 ) = (20×3) + 2( 31 + (16×4)

= 60 + 2( 31 + 64)

= 60 + 2(95)

= 60 + 190

Molar mass of calcium phosphate =

250g/mol

Mass = 20 g

So we have

[tex]n = \frac{20g}{250g/mol} [/tex]

We have the final answer as

n = 0.08 mol

Here, Na = Avagadro Number (6.022 × 10²³)

☀️ As it is a compund, We considered molecules. Then, we can predict the no. of atoms of elements in one molecule of compound and get the answer.

Solution:

Atomic weight of elements:

Ca = 40C = 12O = 16

❍ Molecular weight of [tex]\sf{CaCO_3}[/tex]

= 40 + 12 + 3 × 16

= 52 + 48

= 100 g/mol

❍ Given weight: 10 g

Then, no. of moles,

⇛ No. of moles = 10 g / 100 g mol‐¹

⇛ No. of moles = 0.1 moles

☄ No. of moles of Calcium carbonate in the given weight = 0.1 moles

Finding no. of molecules,

⇛ No. of molecules of CaCO3 = 0.1 × 6.022 × 10²³

⇛ No. of molecules of CaCO3 = 6.022 × 10²²

Now,

1 molecule of [tex]\sf{CaCO_3}[/tex] = 3 atoms of Oxygen.

Then, 6.022 × 10²² molecules will have,

= 18.022 × 10²² atoms of oxygen

In more scientific form,

= 254 (approx.)

❍ Given weight: 12.7

⇛ No. of moles = 12.7 / 254

⇛ No. of moles = 0.05 moles

⚘ No. of moles of Iodine molecule in the given weight = 0.05 moles

━━━━━━━━━━━━━━━━━━━━

Answer:

The answer is 0.05 mol

Explanation:

To find the number of moles (n) we use the formula

[tex]n = \frac{m}{M} [/tex]

Where

n is the number of moles

m is the mass of the substance

M is the molar mass

To find the number of moles we must first find the molar mass

Since iodine is a diatomic molecule

M( I ) = 127 × 2 = 254 g/mol

Mass of iodine = 12.7 g

So the number of moles in 12.7 g of iodine is

[tex]n = \frac{12.7 \: g}{254 \: g/mol} [/tex]

We have the final answer as
