What is the mass of a nitrogen (N2) molecule?

univerkov | August 22, 2021 | education

We calculate the mass of a nitrogen molecule by the formula:
m = M / Na, where m is the mass of one nitrogen molecule (kg), M is the molar mass of nitrogen (nitrogen is a diatomic gas, M = 0.028 kg / mol), Na is Avogadro’s number (Na = 6 * 10 ^ 23 mol ^ -1 ).
Let’s calculate the mass of one nitrogen molecule:
m = M / Na = 0.028 / 6 * 10 ^ 23 = 4.67 * 10 ^ -26 kg.
Answer: The mass of one nitrogen molecule is 4.67 * 10 ^ -26 kg.
