Phosphorus is a non metal. atomic number of it is 15.
i dont know if u what u meant but here's this Atomic Number: 15 Atomic Mass: 30.97376
The number of moles of phosphorus depends on the given quantity or mass of phosphorus. To calculate the number of moles, you need to know the molar mass of phosphorus (about 30.97 g/mol) and the mass of the sample. You can then use the formula moles = mass/molar mass to find the number of moles.
Have different atomic mass (have different numbers of neutrons)
The gram atomic mass of phosphorus is 30.9738, and by definition, a mole of such atoms contains Avogadro's Number of atoms. Therefore, 100 g of phosphorus contains 100/30.9738 or 3.23 moles, to the justified number of significant digits.
First find the atomic numbers of phosphorus and calcium (x3) Then add the numbers together to find the overall atomic number Next divide the atomic number of phosphorus by the overall atomic number and multiply by the number. P=15 Cl=20x3=60 60+15=75 15/75= 0.2x100=20% I think this is right, hope it helps
