The reactants are methane and oxygen.
The products are carbon dioxide and water.
A) covert 0.330g to moles by dividing by molar mass of P2O5 .. Let's call this Y moles
B) 1 mole of anything contains the Avogradro Number of molecules
So here it is 6.02 x 10^23 x Y molecules
C) work out how many atoms in each molecule 2P + 5O total 7
So multiply answer to B by 7 to get final answer
You can simply subtract the atomic number from the mass number in order to find the number of neutrons.
