Given:
     15 g = mass of magnesium hydroxide
     75 ml = volume of solution
Find: % concentration in g/ml
Solution:

% by mass/ volume = [tex] \frac{mass-of-solute}{volume-of-solution} [/tex]
% by mass/ volume = [tex] \frac{15 g}{75 ml} [/tex]
% by mass/ volume = 0.20 g/ml
% by mas/ volume = 20% g/ml
