Answer 2

Hey mate..

Here is your answer-

Ca(H2Po4)2

Molecular mass of Ca(H2Po4)2 is 234.05g

Atomic mass of Phosphorus is 31g

Percentage of Phosphorus is

= Atomic mass of element /Molecular mass of compound × 100

= 31/ 234.05 × 100

= 13.24%

The number of atoms in Ca(H2Po4)2 is 2

Therefore the percentage of phosphorus is

= 13.24 × 2

= 26.48%
