As we learnt

 

Molality -

Molality (m) = (number of moles of solute)/(mass of solvent in kg)

 

- wherein

It is defined as the number of moles of solute present in 1 kg of solvent. It is denoted by m.

 

 Molality = \frac{mass\;of\;solute}{mass\;of\;solution} = \frac{222.6}{62\times0.2} = 17.97m
