Calculate the molality of 1 litre solution of 93% `H_2SO_4` (weight/volume). The density of the solution is `1.84 g ml^(-1)`.

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
Density `= 1.84 g L^(-1)`
Mass of `100 mL` solution `= 100 xx 1.84 = 184 g`
Mass of `H_(2) SO_(4)` in `100 mL` solution `= 93 g`
Mass of water is `100 mL` solution `= 184 - 93 = 91 g`
Molality `= (93)/(98) xx (1)/(91) xx 1000 = 10.428`
