Commercially available cone. HCI contain...

Commercially available cone. HCI contains 38% HCI by mass density of 1.19 g `cm^(3)`. Calculate the molarity of this solution.

Text Solution

Verified by Experts

The correct Answer is:
12.39 M 0.125 M
Mass of HCI in solution = 38 g , Mass os soution = 100 g
Density of solution `=1.19" g mol"^(-3)`
`"Volume of 100 g of solution"=((100g))/((1.19cm^(-3))=84 cm^(3)`.
`"Molarity of solution (M)"=("Mass of HCI/Molar mass")/("Volume of solution in dm"^(-3))=((38.0g)//(36.5" g mol"^(-1)))/(84//1000(DM^(3)))=12.39 m`.
