Question

Equal volumes of two solutions, one containing glucose and another urea have osmotic pressures 12.6 atm and 23.8 atm at 25 °C. Calculate the ratio of number of moles of urea to glucose.

Answer 1

Given : Osmotic pressure of glucose solution 

= π₁ 

= 12.6 atm 

Osmotic pressure of urea solution = π₂ 

= 23.8 atm 

Number of moles of glucose = n₁ 

Number of moles of urea = n₂
