Question

40 ml of H2 S o4 is dissolved in 160 ml of water the volume percentage of the solution is?

Answer 1

Explanation:

Mass of sulphuric acid dissolved in water = density x volume = 1.84 x 10 = 18.4 g. Further, volume of solution = 10+ 90 = 100 ml. So, we see that. 100ml sulphuric acid solution has 18.4 g of H 2 SO 4. So, Concentration of solution(m/V%) = 18.4/100 x100 = 18.4
