Answer 2

Answer:

Hello, thank you for asking the question. The calculation is as follows,

15% acid = 15g/100ml

Density is 1.02g/ml, so that makes 15gm in 102gm of solution

Now subtracting the weight of acid from the total weight of the solution

= 102 g – 15 g

= 87 g of water

To find out how much acid is present in 100g of water, we do the following,

100ml x 87g /15g

= 17.24/100 g of water

The density of water is said to be 1g/ml, therefore its concentration will be 17.24/100 ml or 100g of water

Hence,

The mass by volume percentage of H2SO4 will be 17.24% w/w
