Question

Molarity of liquid HCl will be, if density of solution is 1.17 g / cc (A) 36.5 (B) 32.05 (C) 18.25 (D) 42.10

Density =1.17 g / cc ( Given ) As d=( text Mass / text Volume ) Volume =1 c c ∴ Mass =d=1.17 g Molarity =( text No. of moles / text Volume in litre )=(1.17 × 1000/36.5 × 1) =(1170/36.5)=32.05 M

Q. Molarity of liquid $H Cl$ will be, if density of solution is $1.17 g / cc$

$36.5$

$32.05$

$18.25$

$42.10$

Density $= 1.17 g / cc$ ( Given )
As $d = \frac{Mass}{Volume}$
Volume $= 1 cc$
$∴$ Mass $= d = 1.17 g$
Molarity $= \frac{No. of moles}{Volume in litre} = \frac{1.17 \times 1000}{36.5 \times 1}$
$= \frac{1170}{36.5} = 32.05 M$
