Question

Moles of N = 0.4 and moles of O = 0.1. Find $\left(P_{N_2}\right)$ partial pressure of N at atmospheric pressure

• A. 0.2 atm
• B. 0.8 atm
• C. 0.6 atm
• D. 0.4 atm

Answer 1

Answer: (B)

0.8 atm

Answer 2

Partial pressure = mole fraction $\times$ total pressure $P_{N_2}=\frac{0.4}{0.5}\times1$ = 0.8 atm
