Question

4 gram oxygen and 2 gram hydrogen are kept in a one-litre container at $0^{o}C$. Calculate the total pressure.

Answer 1

Given $4g$ of $O_2$ and $2g$ of $H_2$

$V=1L$ $T=273K$ $R=0.0821\frac{Latm}{molK}$

We have, $PV=nRT$

$P\times 1=[\frac{4}{32}+\frac{2}{2}]0.0821\times 273$

$P=[\frac{1}{8}+1]\times 0.0821\times 273$

$P=\left[\frac{9}{8}\right]\times 22.4133$

$\therefore P=25.21atm$
