Question

3) A flask at 295 K contains a gaseous mixture of N2 and O2 at a total pressue of 1.8 atm.If 0.2 moles of N2 and 0.6 moles of O2 are present, find the partial pressure of N2 and 02 ​

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
