You need to make an aqueous solution of 0.150 M sodium fluoride for an experiment in lab, using a 500 mL volumetric flask. How much solid sodium fluoride should you add?
Answers
Answer:
Explanation:
Solution required is .15 M 500 mL sodium fluoride .
molecular weight of sodium fluoride = 42
one mole of sodium fluoride = 42 grams
No of moles contained in the solution of .15M , 500 mL solution
= .15 x 0.5 moles = .075 moles
1 mole = 42 g
.075 moles = .075 x 42 = 3.15 grams .
So mass of sodium fluoride required = 3.15 g .

Answers
Answer:
Pseudoscience
Explanation:
Predicting the future based solely on the position of the planets is an example of pseudoscience.
Pseudoscience is a body of knowledge that is not based on the scientific method but on some unverifiable/unprovable claims.
Predictions about the future can only be valid if it is based on the scientific method, not just about the position of the planet. The scientific method involves observation, hypothesis formulation, testing of the hypothesis through repeatable experiments, and arriving at conclusion.
Any other statement or belief that is not based on these procedures is said to be pseudoscientific.
Answer:
The answer to your question is pseudoscience.

An object has a volume of 825 cm3 and a density of 13.6 g/cm3. Find its
mass
Answers
step by step explanation:
D= M/V
M= DV
M= (13.6 g/cm^3) (825cm^3)
M= 11,200 g
The mass of an object is the product of its volume and density. The mass of a the object with a volume of 825 cm³ and a density of 13.6 g/cm³ is 11220 g.
What is density ?Density of substance is the measure of its mass per unit volume. It describes how closely its particles are packed. Density depends on the bond type, temperature and pressure.
Volume of the object is the space occupied by its particles. Volume can be expressed in L, ml, cm³, dm³ etc. Only solids and liquids has a definite volume and the volume of gases is that of the container.
Give that, volume of the object = 825 cm³
density = 13.6 g/cm³
Mass = volume × density
m = 825 cm³ × 13.6 g/cm³ = 11220 g
Therefore, the mass of the object is 11220 g.
