Question

In 2 mole of solution mole fraction of water is 0.8. Moles of solute will be ?
​

Answer 1

Answer:

mole fraction of solute+mole fraction of solvent=1

in 2 moles mole fraction of H2O(water) that is the solvent is 0.8

in 1 mol 0.8÷2==0.4

=>mole fraction of solute in 1 mol solution is1-0.4=0.6
