Question

Commercially available concentrated hcl contains 38% hcl by mass. (1) what is the molarity of the solution ( density of solution =1.19 g ml -1)

Answer 1

Answer:

12.3M

Explanation:

$molarity = 10 \times density \: of \: solution \times mass\% \div molar \: mass \: of \: solute \\ m = 10 \times 1.19 \times 38 \div 36.5 \\ m = 12.38$
