The amount of the nitrogen gas, N₂ molecules present is 2.68×10²² molecules
Avogadro's hypothesis
1 mole of N₂ = 6.02×10²³ molecules
How to determine the mole of N₂
We'll begin by calculating the number of mole of N₂. This can be obtained as follow:
- Mass of N₂ = 1.25 g
- Molar mass of N₂ = 28.02 g/mol
- Mole of N₂ =?
Mole = mass / molar mass
Mole of N₂ = 1.25 / 28.02
Mole of N₂ = 0.0446 mole
How to determine the molecules of N₂ present
From Avogadro's hypothesis,
1 mole of N₂ = 6.02×10²³ molecules
Therefore,
0.0446 mole N₂ = 0.0446 × 6.02×10²³
0.0446 mole N₂ = 2.68×10²² molecules
Thus, the molecules of N₂ present is 2.68×10²² molecules
