clacuate the number of moles of phosphurs atoms in 100g of phosphurs if phosphurs is considered to contain P4 moluclues then how many moles it has (atomic mass of khakhors=31) explain

Solution :

 

 

Mass of 1 mole of P₄ = 4 × 31 = 124g

Therefore, Moles in 100 g of P₄ = 100   =0.806 moles

                                                 124

So, there are 0.806 moles of P4 in 100 g of it.
