find Mass by volume percentage of 15% solution of H2SO4 .( density = 1

1.	find Mass by volume percentage of 15% solution of H2SO4 .( density = 1.02gml-1)
Answer» What is the answer?? don't know this question was given to me for assignment The solution has 15% acid, means 15g/100ml.The density is of solution is 1.02g/ml.Mass of solution having 15g of acid= density × volume= 1.02 g/ml × 100 ml=102 gSo, mass of water = mass of solution-mass of acid=102 – 15=87 g Acid present with 87 g of water is 15 g.So, acid present with 100 g of water.=100 X 87/15 = 17.24/100 g of waterThe density of water is 1g/ml.So, the concentration will be 17.24/100 ml of water.So, the mass by volume percentage is 17.24 %.

don't know

this question was given to me for assignment

The solution has 15% acid, means 15g/100ml.The density is of solution is 1.02g/ml.Mass of solution having 15g of acid= density × volume= 1.02 g/ml × 100 ml=102 gSo, mass of water = mass of solution-mass of acid=102 – 15=87 g Acid present with 87 g of water is 15 g.So, acid present with 100 g of water.=100 X 87/15 = 17.24/100 g of waterThe density of water is 1g/ml.So, the concentration will be 17.24/100 ml of water.So, the mass by volume percentage is 17.24 %.
