SUMMARY
The weight percentage of Nitrogen in air is approximately 76%, derived from its volumetric composition of 78% Nitrogen, 21% Oxygen, and 1% Argon. The atomic weights used in the calculation are 14 for Nitrogen, 16 for Oxygen, and 40 for Argon. The calculation involves determining the total weight of the gases and finding the proportion of Nitrogen's weight relative to the total. The final result can vary slightly based on significant figures, but for practical purposes, it is accepted as 76%.
