Question

a solution contains 0.25 mole of solute and 0.75 mole of solvent calculate mole fraction of solvent in the solution

Answer 1

Answer:

mole fraction of solvent is 0.75

Explanation:

Given

no of moles of solute = 0.25mole

no of moles of solvent = 0.75 Mole

to find mole fraction of solvent

no of mole of solution= number of moles of solute

+ number of moles of solvent

number of moles of solution = 0.25+0.75=1

mole fraction of solvent =

number of moles of solvent ÷number of moles of solution

mole fraction of solvent= 0.75 ÷ 1 = 0.75
