Question

Our atmosphere is made up of 78% N2, 21% O2, and 1% other gases. What is the partial pressure of N2 when atmospheric pressure is 0.980 atm?

Answer 1

Answer: 0.7644 atm

Explanation:

Given,

Total atmospheric pressure= 0.980atm

Percentage of N₂=78%=0.78

Partial Pressure of N₂=Total atmospheric pressure*Percentage of N₂

=0.980 atm × 0.78

=0.7644 atm
