Question

68:4 g urea is present in 1l solution? find the molarity of
sole if it is diluted 10 time ​

Answer 1

Explanation:

Moles of urea =12/60=0.2

Moles of sucrose =68.4/342=0.2

(molar mass of sucrose is 342gm )

Since there are equal moles of solute in equal volumes of water, the mole fraction is same.

As per Raoult's law, the relative lowering of pressure is also same.
