Question

4.
A 10 dm' flask at 300 K contains a gaseous
mixture of CO and CO2 at a total pressure of
0.821 atm. If 2/3 moles of CO is present, find its
partial pressure and also that of CO2-​

Answer 1

Answer:

Total moles =

RT

PV

=

298×0.0821

2×10

=0.8174

Moles of CO

2

=0.8174−0.2=0.6174

Partial pressure of CO= X

CO

×2=

0.8174

0.2

×2=0.4893 atm

Partial pressure of CO

2

=2−0.4893=1.51 atm
