Question

What is the molarity of HCL solution that has a density of 1.17g/ml at 25°?​

Answer 1

32.05

Molarity=

molarmass

density×1000moles/litre

Molar mass of HCl = 1+35.5

=36.5g/mol

Molarity =

36.5

1.17×1000

=32.05

Answer 2

~Solution :-

Here, we have been given that;

• $ \bf{1 ml}$ = 1.17 g
• $ \bf{1 l}$ = 1170 g

Hence, we can note that,

• No. of moles of HCL (n) = $ \sf{\frac{1170}{36.5}}$

(n) = 32.05

Thus,

• Molarity = 32.05 mg/L

Hence, molarity of the given solution will be 32.05 mg/L.
