36.5% `HCl` has density has density equal to `1.20 g mL^(-1)`. The molarity `(M)` and molality `(m)`, respectively, are

A

15.7,15.7

B

12,12

C

15.7,12

D

12,15.7

Text Solution

Verified by Experts

The correct Answer is:
D
`M = (% "by weight" xx 10 xx d)/(Mw_(2)) = (36.5 xx 10 xx 1.2)/(36.5) = 12 M`
`m = (36.5 xx 1000)/(36.5 xx (100 - 36.5)) = (1000)/(36.5) = 15.7 m`
