30% (w/v) of H2SO4 solution. Calculate % (v/w), if density of H2SO4 is 1.05 g/ml and density of solution is 1.5g/ml.

30% w/v H2SO4 means 30 g H2SOin 100 ml solution.
 
Mass of H2SO4 = 30 g
Density of H2SO4 = 1.05 g/ml
Volume of H2SO4 = Mass/Density = (30 g)/(1.05g/ml) = 28.57 ml
 
Volume of solution = 100 ml
Density of solution = 1.5 g/ml
Mass of solution = Volume*Density = (100 ml)*(1.5 g/ml) = 150 g
 
So,  
 
% w/v, & v/w, h2so4
Hence, %v/w = 19.046 %
