A vessel contains equal masses of $C H_{4}$ , $O_{2}$ and $He$ and recorded a total pressure of 5.5 bar at 25° $C$ . Find the partial pressure of $C H_{4}$ (in bar) in the vessel

Options:

Answer:

Solution:

For equal mass m, moles = m/ $M$ . $n$ ( $C H_{4}$ ) : $n$ ( $O_{2}$ ) : $n$ ( $He$ ) = 1/16 : 1/32 : 1/4 = 2 : 1 : 8.

Mole fraction of $C H_{4}$ = 2/11.

$P$ ( $C H_{4}$ ) = 5.5 x 2/11 = 1.0 bar.

Answer: (B).
