In Victor Meyer's experiment, 0.23 g of a volatile solute displaced air which measures 112 mL at NTP. The vapour density is ______.

Open in App

Solution

$Volume occupied by solute at NTP =Volume of air displaced at NTP = 112 m l$
Also,
$P = 1 a t m, T = 273 K, w = 0.23 g$
$∴ P V = \frac{w}{M} R T$
$1 \times \frac{112}{1000} = \frac{0.23}{M} \times 0.0821 \times 273$
$∴ M = 46 g$
Also as we know,
$M = V . D \times 2$
Vapour Density $= 23$
