Answer 41

% w/w = (Mass of solute / Mass of solution) * 100

Question 42

Percent solution (v/v)

Answer 42

% v/v = (Volume of solute / Volume of solution) * 100

Question 43

Dilution (simple)

Answer 43

Simple dilution = (Volume of sample / Total volume of solution)

Question 44

Dilution of stock solution

Answer 44

Dilution of stock = C1 * V1 = C2 * V2 (C1 = initial concentration, V1 = initial volume, C2 = final concentration, V2 = final volume)

Question 45

Dilution of sample

Answer 45

Dilution of sample = C1 * V1 = C2 * V2 (C1 = initial concentration, V1 = initial volume, C2 = final concentration, V2 = final volume)

Question 46

Ratio

Answer 46

Ratio = Amount of solute / Amount of solvent or solution (part per part or part per whole)
