Commercially available concentrated HCI ...

Commercially available concentrated HCI contains 38.0% HCl by mass (density = 1.19 `g mL^(-1) ` ). The molarity of the solution is

A

10.40 M

B

5.70 M

C

12.38 M

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)`
Molarity ` = ( (38)/(36.5) xx 1000)/( (100)/(1.19) ) = 12.28M `
