How many atoms are in 1.5 moles of iron?

The number of atoms present is 1.5 moles of iron is 9.0 ×10²³ atoms

From the question,

We are to determine the number of atoms present in 1.5 moles of iron.

From the formula,

Then, we can write that

Number of atoms = Number of moles × Avogadro's constant

∴ Number of atoms of iron present = 1.5 × 6.022×10²³

Number of atoms of iron present = 9.033 ×10²³ atoms

Number of atoms of iron present ≅ 9.0 ×10²³ atoms

Hence, the number of atoms present is 1.5 moles of iron is 9.0 ×10²³ atoms
