Superphosphate formula CaH4 (PO4)2 H2O. Answered

Superphosphate has the formula CaH4 (PO4)H2O.
Can someone help me calculate the percentage of Phosphorus in this chemical showing the calculation please?

thank you



Check the atomic mass of each element.
Multiply each mass by the number of atoms in the molecule (eg there are ten oxygens), then total those masses.
You can then calculate the mass of the phosphorus as a percentage of the total.
