HELLO,
you have 15% acid that means 15g/100ml
the density is 1.02g/ml,so the 15gm are in 102gm of solution
Now substract the weight of acid from the total weight i,e
=>102 – 15
=>87 g of water
All you need to know is to find how much of it will be present in 100g of water 
100 X 87/15 
= 17.24/100 g of water
The density of water is 1g/ml,so the concentration will be 17.24/100 ml or 100g of water
so the mass by volume percentage will be 17.24% w/w
THANK YOU
