Calculate the mass of the following

6.022 × 10²³ number of N₂ molecules.

6.022 X 10²³ number of N₂ molecules.

As we know that 1 mole = 6.022 X 10²³atoms

For 1 mole of N₂ molecules:

First, we apply the formula:

⇒ Mass of N₂ = No. of moles × Molar mass of N₂

⇒ Mass of N₂ = 1 mole × 2(atomic mass of nitrogen)

⇒ Mass of N₂ = 1mole × 28u

⇒ Mass of N₂ = 28g

Thus, mass of 6.022 × 10²³ number of N₂ molecules is 28g.
