Question

Calculate mole fraction of solute in 2.5 m aqueous solution

Answer 1

Answer:

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

Number of moles of water =100018gmol−1100018gmol−1

⇒55.55⇒55.55

Total number of moles =2.5+55.55

⇒58.05⇒58.05

Mole fraction of solute =2.558.052.558.05

⇒0.043
