Explanation:
The number of moles of methane is
16
3.2
=0.2.
The pressure exerted by methane is P=
V
nRT
=
9×10
−3
0.2×8.314×300
=5.54×10
4
Pa.
The number of moles of CO
2
is
44
4.4
=0.1.
The pressure exerted by CO
2
is P

=
V
n

RT
=
9×10
−3
0.1×8.314×300
=2.77×10
4
Pa.
The total pressure is P+P
′
=5.54×10
4
Pa+2.77×10
4
Pa=8.31×10
4
Pa.
