Question

Vinegar is commonly sold as a 5 percent (v/v) solution of acetic acid in water. This measurement means which of the following?


5 grams of acetic acid/100 grams of solution

5 grams of acetic acid/100 grams of water

5 mL of acetic acid/100 mL of solution

5 mL of acetic acid/100 mL of water

Answer 1

Vinegar is commonly sold as a 5 percent (v/v) solution of acetic acid in water. This measurement means 5 mL of acetic acid/100 mL of solution.

Answer 2

Answer:

The correct answer is : 5 mL of acetic acid/100 mL of solution

Explanation:

The 5 percent (v/v) measurement tells us about volume of the pure acetic acid in an overall solution.

Suppose in 1000 mL of solution , the volume of acetic acid be x

$5\%=\frac{x}{1000 mL}\times 100$

x = 50 mL

Similarly in 100 ml of solution, let the of acetic acid volume be y.

$5\%=\frac{y}{100 mL}\times 100$

y = 5 mL
