Answer to Question #254637 in Chemistry for MAYMAY

Question

a bottle of hydrogen peroxide also known as agua oxigenada is labeled 3% (v/v). How many ml of agua oxigenada are in a 400ml bottle of this solution?

Answer 1

Solution:

Solute = agua oxigenada

(v/v)% = 3%

Volume of agua oxigenada = unknown

Volume of solution = 400 mL

The equation for volume percent of a solution:

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

Therefore,

3% = (Volume of agua oxigenada / 400 mL) × 100%

0.03 = Volume of agua oxigenada / 400 mL

Volume of agua oxigenada = (400 mL × 0.03) = 12 mL

Volume of agua oxigenada = 12 mL

Answer: 12 mL of agua oxigenada is in a 400 mL bottle of the solution.
