Answer:
Explanation: first of all molality formula=no. of moles of solute in 1 kg of solvent
m=(Wb*1000)/Mb*Ma
where Wb=mass of given solute
Ma=molar mass of given solvent in kg
Mb= molar mass of given solute
so already given that no. of moles that is Wb/Mb=5
so
m=5*1000/250
m=5*4
m=20 mol/kg
hope it helps
