Question

A pre-weighed vessel was filled with oxygen at NTP and weighed. It was then evacuated, filled with SO2 at the same temperature and pressure, and again weighed. The weight of oxygen is

Options

A.The same as that of SO2
B.1/2 that of SO2
C.Twice that of SO2
D.1 / 4 that of SO2

Solution

$\frac{w_{O_{2}}}{32} = \frac{w_{SO_{2}}}{64} \Rightarrow w_{O_{2}} = \frac{1}{2} \times w_{SO_{2}}$
