Answer:
Partial pressure of nitrogen gas,[tex]p^o_{N_2] =0.44 atm[/tex]
Explanation:
Pressure of the mixture of gases before adding nitrogen gas = 0.85 atm
Pressure of the mixture of gases after adding nitrogen gas = 988 mmHg
1 mmHg = 0.001315 atm
988 mmHg=[tex]988 mmHg\times 0.001315 atm = 1.29 atm[/tex]
Partial pressure of nitrogen gas,[tex]p^o_{N_2] = 1.29 atm - 0.85 atm = 0.44 atm[/tex]
According to Dalton's law of partial pressure , the total pressure of the mixture of gases is equal to sum of all the partial pressures of each gas present in the mixture.
[tex]P_{total}=\sum p^o_{i}[/tex]
So, on addition of nitrogen gas to the mixture the pressure of the mixture increases.
