Molality of solution is 16 mole/kg

Explanation:

Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

Molarity=\frac{n}{W_s}

where,

n = moles of solute

W_s = weight of solvent in kg

moles of water (solvent )= 0.78

moles of HCl (solute) = (1-0.78) =0.22  

mass of water (solvent )= moles\times {\text {Molar Mass}}=0.78\times 18=14g=0.014kg

Now put all the given values in the formula of molality, we get

Molality=\frac{0.22}{0.014kg}=16mole/kg

Therefore, the molality of solution is 16 mole/kg
