Calculate the number of atoms in 0.316 mol of phosphorus

The number of atoms of phosphorus are

Explanation:

We are given:

Number of moles of phosphorus = 0.316 moles

According to mole concept:

1 mole of an element contains number of atoms

So, 0.316 moles of phosphorus will be present in number of atoms

Hence, the number of atoms of phosphorus are
