Question

Two identical vessels are filled with 44 g of hydrogen and 44 g of carbon dioxide at the same temperature. If pressure of $C{O}_2$ is 2 atm. Find the pressure of hydrogen.

• A. $P_{H_2}=56atm$
• B. $P_{H_2}=44atm$
• C. $P_{H_2}=32atm$
• D. None of these

Answer 1

The correct option is B $P_{H_2}=44atm$

Two identical vessels,

$44g$ of $C{O}_2=1mol$ and exerts $2atm$ pressure.

Now,

$44g$ of $H_2=\frac{44}{2}=22mol$ and hence, will exert $=22\times 2atm$ pressure.

$\therefore$ Pressure of $H_2=44atm$.
