Answer:

Given

mass of solute (m) =50g

volume of water( v) 213m

Sln we Know density of water 1g/ml

find mass of water

D=m/v

1g/ml=m/213ml (divided by 213 ml both sides)

m =4.69xe-3

mass of solvent =4.69xe-3

mr of NaCl=23+35.5

mr=58.5

Form our formula of Malality

M=50x1000/58.5x4.69xe-3

M=182.24e3
