Question

The density of $O_2$ at NTP is 1.429 g/L the standard molar volume :-

• A. $22.4L$
• B. $11.2L$
• C. $33.6L$
• D. $5.6L$

Answer 1

The correct option is A $22.4L$

Density of $o_2=$1.429 g/lil

Molar mass = 16$\times$2

=32g/hole

using the formula

Density = mass/volume $\Rightarrow$ 1.42T= $\frac{32}{v}$

volume = 22.39 lit

=22.4 lit

Hence the standard total volume of the

gas $o_2$ is 22.44 lit
