Question

How many grams of KBr could be recovered by evaporating 250.0 mL of a 15.0% mass by volume KBr solution?

Answer 1

Answer #1

Given:

Volume of solution = 250.0 mL

(m/v)% = 15.0 %

Use:

(m/v)% = mass of KBr * 100 / volume of solution

15.0 = mass of KBr * 100 / 250.0

mass of KBr = 37.5 g

Answer: 37.5 g
