7.50 g of NH4Cl is added to 16.6 g of water. Calculate the molality of the solution.

Please show all steps!

Expert Solution

Given mass of NH₄Cl is , m = 7.50 g

Mass of water , W = 16.6 g = 0.0166 Kg

Molar mass of NH₄Cl is = sum of the atomic masses

= atomic mass of N + (4 x atomic mass of H) + atomic mass of Cl

= 14 +(4x 1 ) + 35.5

= 53.5 g mol^-1

We know that molarity ,
