0.02 mole of urea
is dissolved in 250ml of solution. if density of solution is 1.10 g/ml . calculate percentage weight by weight and percentage weight by volume ?
0.02 mol urea x (1 mol/60.06) = 1.20 g.
mass solution = volume x density = ?
%by mass = [mass urea/mass solution]*100 = ?
% by volume = [mass urea/250]*100 = ?
