Question

the molefraction of a solute is 2.5m aqueous solution is

Answer 1

2.5m aqueous solution contains 2.5 moles of solute in 1000g of water.

Number of moles of water =1000/18gmol−1

⇒55.55

Total number of moles =2.5+55.55

⇒58.05

Mole fraction of solute =2.5/58.05

⇒0.043

Answer 2

answer 0.043

thankyou.
