The Correct Option is
C
Solution and Explanation
The total atmospheric pressure is approximately \( 1 \, \text{atm} = 101325 \, \text{Pa} \).
The percentage of nitrogen gas (\( N_2 \)) in the atmosphere is approximately \( 78\% \).
Partial pressure: \[ P_{N_2} = 0.78 \times 101325 \approx 7.9 \times 10^4 \, \text{Pa}. \]
