Commercially available concentrated hydrochloric acid contains 38 % HCl by mass. (i) What is the molarity of the solution if its density is `1.19 "g cm"^(-3)` ?
(ii) What volume of concentrated HCl is needed to make 1.0 L of 0.2 M HCl solution ?

A

10-40 M

B

5-70 M

C

12.38M

D

13.46 M

Text Solution

Verified by Experts

The correct Answer is:
C
38 g of HCl is present in 100 g of solution
Vol. of solution `=100/1.19`
Moalrity `=((38/38.5) xx 1000)/(100/1.19)`
=12.38 M
