What is the mole fraction of the solute in 2.5 m aqueous solution?

Text Solution

Verified by Experts

2.5 m aqueous solution means that 2.5 moles of solute are present in 1000 g of water. Thus,
Moles of solute = 2.5 mol
Moles of water `=1000/18 = 55.6`
Mole fraction of solute `=2.5/(2.5 + 55.6)= 0.043`
