    • Molality is defined as the number of moles of solute present in 1 kg of solvent, it is denoted by m. Thus, Molality(m)=Moles of solute/Mass of solvent(∈kg) Given that, Mass of solvent (H2O)=500g=0.5kg Weight of HCl=18.25g Molecular weight of HCl=1×1+1×35.5=36.5g Moles of HCl=18.25/36.5=0.5 m=0.5/0.5=1m
