Question

0.5 mole of N atoms - Calculate the mass of it.

Answer 1

Answer ⇒ 3.011 × 10²³ atoms.

Solution ⇒

No. of moles of Nitrogen atoms = 0.5

Avogadro's number = 6.022 × 10²³

Using the Formula,

No. of atoms = No. of moles × Avogadro's number.

∴ No. of atoms = 0.5 × 6.022 × 10²³

∴ No. of atoms = 3.011 × 10²³ atoms.

Hence, the number of the atoms in 0.5 mole of the N atoms is 3.011 × 10²³.

Hope it helps.
