Also explain the mathematical relation between specific gravity and concentration of solution.How do we calculate percentage of Zn in Zinc sulphate hepta hydrate?
zinc sulphate heptahydrate= ZnSO4.7H2O
ZnSO4.7H2O= 287.54 g/mole
Zn= 65.38 g/mole
% Zn= Zn/ZnSO4.7H20 x 100
% Zn= 65.38/287.54 x 100= 12.3 %
As solute(density %26gt;1) is added to water, its conc. increases and it density increases
