Question

Four one liter flasks are separately filled with the gases $H_2,He,O_2,O_3$ at the same temperature and pressure. The ratio of the weights of these gases is:

• A. 1:1:1:1
• B. 2:1:2:3
• C. 1:2:16:24
• D. 2:1:16:24

Answer 1

The correct option is C 1:2:16:24

The gases are $H_2$, $He$, $O_2$, $O_3$

The weight of the gases are:

$H_2$ = 2 g/mol

$He$ = 4 g/mol

$O_2$ = 32 g/mol

$O_3$ = 48 g/mol

The ratio of all the gases are $=2:4:32:48=1:2:16:24$
