High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to
purify chemical substances. The pressures used in this procedure range from around 500
kilopascals (500,000 Pa) to about 60,000 kPa (60,000,000 Pa). It is often convenient to know
the pressure in torr. If an HPLC procedure is running at a pressure of 3.20x10^8 Pa , what is its
running pressure in torr?
Express the pressure numerically in torr.

3.20 x 10^8 Pa = _____ torr

Answers

Answer:

2,400,000 torr (3 s.f.)

Explanation:

Convert the pressure from Pascal to atm first:

[tex]\boxed{1 \: atm = 101325 \:Pa }[/tex]

3.20 ×10⁸ Pa

= [(3.20 ×10⁸) ÷101325] atm

= 3158.2 atm (5 s.f.)

Convert atm to torr:

[tex]\boxed{1 \: atm = 760 \: torr}[/tex]

3158.2 atm

= (3158.2 ×760) torr

= 2400000 torr (3 s.f.)

You work in the special effects department of a movie studio. You are currently working on a superhero movie where the hero is very strong and cannot be hurt by normal weapons such as a sword. In the next scene, the villain is going to hit the hero with a lead pipe. The hero's costume is mostly made of foam and carbon so that is it very light and easy to move around in but will crumble if hit with anything hard. For this scene, a section of the costume needs to be replaced with a different material that will only dent, not crumble, when hit with the pipe. You are on a deadline and look around the props department for ideas, what could you use?

Answers

Answer:

Aluminum or Galvanized iron

Explanation:

If the costume has to be such that the hero does not get hurt when hit by a lead rod and also is easy for the mobility then the suitable option for the costume could be Aluminum material which will only dent and not crumble.

Galvanized iron could be another choice being harder and stronger as compared to aluminum but a little heavy. It can sustain heavy impacts as compared to aluminum.

What happens to a glass of sugar solution when sugar is added to it?

The number of moles of water decreases.
The molarity of the solution increases.
The molarity of the solution decreases.

Answers

When sugar is added to a glass of sugar solution, the molarity of the solution increases. Details about molarity can be found below, which is the third option.

What is molarity?

Molarity is a term used to identify the amount of solute, in moles, dissolved in a solvent by volume. Molarity is expressed as moles per liter (mol/L).

However, molarity is directly proportional to the amount of solute in solution. This means that as the amount of solute increases, molarity also increases.

Therefore, when sugar is added to a glass of sugar solution, the molarity of the solution increases.

Describe weighted average

Answers

Answer:

Explained below

Explanation:

In simple average, we just add all the given data variables and divide it by the number of data given.

However, when it comes to weighted average, what we do is that we multiply each given variable by their weights and then divide the sum of that by the sum of the weights.

Thus, if the variables are denoted by x and their weights are denoted by y, then we have;

Determine the mass of 6.33 mol of iron(II) nitrate.

Answers

Answer:

1822.72 g

Explanation:

Applying,

n = R.M/M.M.................. Equation 1

Where n = number of moles of iron(II) nitrate, R.M = Reacting mass of iron(II) nitrate, M.M = molar mass of Iron(II) nitrate.

Make R.M the subject of the equation

R.M = n×M.M............. Equation 2

From the question,

Given: n = 6.33 mol

Constant: M.M of iron(II) nitrate = 287.95 g/mol

Substitute these values into equation 2

R.M = 6.33(287.95)

R.M = 1822.72 g

Hence the mass of iron(II) nitrate is 1822.72 g

Answers

Answer:

a) Solution 1: Solute is ethyl alcohol, solvent is water. Solution 2 and 3: Solute is salt, solvent is water.

b) Concentration by weight of solution 3: Approximately 3.85%.

c) Solution 3 has a higher concentration than solution 2.

a) Solutions and their solutes and solvents:

Solution 1: The solute is ethyl alcohol, and the solvent is water. This is because ethyl alcohol is the substance that dissolves in water to form the solution.

Solution 2: The solute is salt, and the solvent is water. Salt is the substance that dissolves in water to form the solution.

Solution 3: The solute is salt, and the solvent is water. Similar to solution 2, salt is the substance that dissolves in water to form the solution.

b) Weight concentration of solution number 3:

The weight concentration is calculated by dividing the mass of the solute (80 g of salt) by the total mass of the solution (80 g of salt + 2000 g of water):

Weight concentration = (80 g / 2080 g) * 100% ≈ 3.85%

c) Comparison of concentrations between solution 2 and 3:

Solution number 3 has a higher concentration than solution 2, as the weight concentration of solution 3 is approximately 3.85%, while the exact amount of water is not provided for solution 2 to calculate its concentration. However, solution 2 contains only 20 g of salt dissolved in 500 ml of water, which implies that the concentration will be lower than solution 3. Therefore, solution number 3 has a higher concentration compared to solution 2.
