see molality is moles/mass of solvent (in kg)
so the formula for moles is given the mass of the compound/ molar mass of the compound
so here 4/40(40 NaOH molecular mass)=0.1 moles
and the solvent mass is also given but in grams so to convert in kilograms we need to divide by 1000
200/1000=0.2 kilograms
0.1/0.2=0.5m
