If x molal solution of a compound in benzene has mole fraction of solute equal to 0.4 then the value of x is.....
Verified Answer
If x molal solution of a compound in benzene has mole fraction of solu...
Molality = Moles of solute / Weight of Solvent in kg

x = n / 1000

n = 10000x


Mole fraction of solute given is 0.4

0.4 = 1000x / (1000x + 1000/78)

0.4 = 1000x / (1000x + 12.82)

5.128 + 400x = 1000x

x = 117.0 m


Value of x is 117.0 m
