5.6 xx 6.022 xx 10^23"atoms"

Explanation:

A mole of "PCl"_3 contains

  • one mole of "P"
  • three moles of "Cl"

Therefore, you get a total of 4 moles of atoms per mole of "PCl"_3. This means that 1.4 moles of "PCl"_3 contain

1.4 xx 4 = "5.6 moles of atoms"

Each mole of atoms contains Avogadro's number, 6.022 xx 10^23, of atoms. Therefore, the sample contains

5.6 xx 6.022 xx 10^23"atoms".
