Question

in a mixture of 72 gm water and 92 gm ethyl alcohol calculate the mole fraction for both

Answer 1

72 gm of water means 4 moles of water.

92 gm ethyl alcohol means 2 moles of ethyl alcohol.

Mole fraction of water= no of moles of water/ total no of moles

Mole fraction of water= 4/4+2= 4/6= 0.66

Mole fraction of ethyl alcohol= 1 – 0.66= 0.34
