Question

Calculate molarity of liquid $HCl$ if density of liq. $HCl$ is 1.17 gm/cc.

• A. 36.5
• B. 18.25
• C. 32.05
• D. 42.1

Answer 1

The correct option is C 32.05

We have

In $1cc$ volume $=1.17g$ of $HCl$

$1cc=0.001L$

Moles of $HCl=$ $\frac{1.17}{36.5}=0.032$

Molarity $=$ $\frac{0.032}{0.001}=32.05M$
