Find the mass of the nitrogen molecule (N2).
| July 6, 2021 | education
To calculate the mass of a nitrogen molecule, we use the formula m = M / Na
M (molar mass of nitrogen), given that the nitrogen molecule consists of two atoms, we take M = 0.028 kg / mol);
Na is a constant (Avogadro’s number) equal to 6 * 10 ^ 23 mol ^ -1.
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.
