Question

510 mg of liquid on vaporization in Victor Meyer’s apparatus displaces 67.2 cm3 of air at (STP). The molecular weight of the liquid is - (A) 130 (B) 17 (C) 170 (D) 1700

Tardigrade Admin · Accepted Answer

Mol. wt. of liquid =(510×10-3/67.2)×22400=170

Q. $510 m g$ of liquid on vaporization in Victor Meyer’s apparatus displaces $67.2 c m^{3}$ of air at $(STP)$ . The molecular weight of the liquid is -

$130$

$17$

$170$

$1700$

Mol. wt. of liquid
$= \frac{510 \times 1 0 ^{- 3}}{67.2} \times 22400 = 170$
