An aqueous solution of urea containing $18 g$ urea in $1500 cm^{3}$ of the solution has a density equal to $1.052$ . If the molecular weight of urea is 60, the molality of the solution is

Options:

Answer:

Solution:

$1500 cc . solution = 1500 \times 1.052 g$ $= 1578 g$ Weight of solvent $= 1560 g$ Weight of solute $= 18 g$ Molality $= \frac{weight of solute}{molecular weight of solute \times}$ weight of solvent in $kg$ $= \frac{18 \times 1000}{60 \times 1560}$ $= 0.192 m$
