What is the approximate percentage of nitrogen in air?
Answer and explanation
Correct answer: 78%
Nitrogen forms approximately 78% of dry air, so option C is correct. Oxygen is the next major component at about 21%, while argon and other gases together account for roughly 1%. Carbon dioxide is present in a much smaller amount, close to 0.04%. Thus, comparing the standard composition of air clearly identifies 78% as the percentage of nitrogen.
