Question

A pre-weighed vessel was filled with oxygen at NTP and weighted. It was then evacuated, filled with SO2 at the same temperature and pressure, and again weighted. The weight of oxygen will be (A) The same as that of SO2 (B) (1/2) that of SO2 (C) Twice that of SO2 (D) One-fourth that of SO2

( textM. wt. of O2/ textM. w t.of SO2) ⇒ (M1/M2) ⇒ (32/34)=(1/2) The weight of oxygen will be (1/2) that of SO2

Q. A pre-weighed vessel was filled with oxygen at $NTP$ and weighted. It was then evacuated, filled with $S O_{2}$ at the same temperature and pressure, and again weighted. The weight of oxygen will be

The same as that of $S O_{2}$

$\frac{1}{2}$ that of $S O_{2}$

Twice that of $S O_{2}$

One-fourth that of $S O_{2}$

$\frac{M. wt. of O _{2}}{M. w t.of S O _{2}}$
$\Rightarrow \frac{M _{1}}{M _{2}} \Rightarrow \frac{32}{34} = \frac{1}{2}$
The weight of oxygen will be $\frac{1}{2}$ that of $S O_{2}$
