Question

Equal masses of CH4 and H2 are mixed in a container at 298K.Fraction of total pressure exerted by methane is

a) 1/2
b) 1/3
c) 1/9
d) 8/9

Answer 1

Equal masses of CH4 and H2 are mixed in a container at 298K.Fraction of total pressure exerted by methane is

a) 1/2

b) 1/3

c) 1/9

d) 8/9✔✔

Explanation:
The idea here is that the partial pressure of hydrogen gas will depend on

the mole fraction of hydrogen gas in the mixture
the total pressure of the mixture
Now, let's say that we are mixing
m

g
of hydrogen gas and
m

g
of methane.

Use the molar masses of the two gases to expres
