what's is the molecular formula of 1.24gram of phosphorus molecules ?

Question

class 9 chemistry

Answer 1

The molecular formula?  Phosphorus has the symbol P.  If you are asking how many atoms (not molecules) there are in 1.24 g of P, that is one thing.  Or perhaps you are asking about white phosphorus, which does exist as a molecule, and it represented as P₄.  Your question is not clear, unfortunately.
