Question

Concentrated hydrochloric acid contains 37 % HCl (by mass). The density of this solution is 1.18 g / mL. The molarity (conc. in mol L L -1 ) of solution is (A) 10 M (B) 12 M (C) 13 M (D) 14 M

As in 78 (37 × 1000 × 1.18/100 × 36.5)=12 M

Q. Concentrated hydrochloric acid contains $37% H Cl$ (by mass). The density of this solution is $1.18 g / m L$ . The molarity (conc. in mol L $L^{- 1}$ ) of solution is

$10 M$

$12 M$

$13 M$

$14 M$

As in $78$
$\frac{37 \times 1000 \times 1.18}{100 \times 36.5} = 12 M$
