Commerically available concentrated hydrochloric acid contains 38% HCl by mass and density `1.19 g cm^(-3)` . Calculate the molarity of this solution.

Text Solution

Verified by Experts

The correct Answer is:
12.4 M
Moles of HCl `= (38)/(36.5)`
Volume of solution `= (100)1.19) = 84.03 mL`
Molarity `= (38//36.5)/(84.03) xx 1000 = 12.39 M`
