Question

Calculate the molarity of a solution of ethanol in water in which the mole fraction of ethanol is 0.040​

Answer 1

Answer:

3.0/5

11

mole fraction=0.04

So if one molof solution contain 0.04 mol of ethanol and (1-0.04)molof water=0.96

So the mass of water=0.96*18 g=17.28g

So the mass of ethanol=0.04*46 g=1.84g

total mass=18.92g

Assuming the density of solution to be 1g/ml, the vlume of the solution=18.92ml

So if18.92ml of solution conta
