Question
What is the % mass of 12 M hydrochloric acid. Density of 12 M hydrochloric acid solution is 1.18 g/mL and the density of water is 1.00 g/mL
Answers

% w/w = (grams HCl/100 g soln)*100
12M is 12 mols/L soln
12 mols = 12*36.5 g/mol = about 438 g HCl
mass 1000 mL = 1180 grams (1.18 x 1000)
(438/1180)*100 = ? w/w
