Question

Find out the mass by volume percentage of 15 solution of sulphuric acid density 1.02 g / ml

Answer 1

Answer:

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%

hope it helps you
