$12 g$ of a nonvolatile solute dissolved in $108 g$ of water produces the relative lowering of vapour pressure of $0.1$ . The molecular mass of the solute is :

Options:

Answer:

Solution:

$\frac{P ^{o} - P _{s}}{P ^{o}} = \frac{n}{N} = \frac{w}{m} \times \frac{M}{W}$ $0.1 = \frac{12}{m} \times \frac{18}{108}$ $m = \frac{12 \times 18}{0.1 \times 108} = 20$
