Given information

The mass percent composition of calcium phosphate is   .    

The amount of phosphorus is    

 

Step-by-step explanation

Step 1.

The given compound is Calcium phosphate.

The chemical formula of the given compound is .

The formula to calculate formula mass is,

 

Where,

  • represents the number of atoms of the first element in the chemical formula.

  • represents the atomic mass of the first element.

  • represents the number of atoms of the second element in the chemical formula.

  • represents the atomic mass of the second element.

The atomic mass of calcium is  

The atomic mass of phosphorus is .

The atomic mass of oxygen is    

Substitute the value of atomic mass in the above formula,

 

                           

                             

 

The formula mass or molar mass of is    

The mass percent composition of calcium phosphate is  

The percentage of is given, assuming that the total mass is .

This means that the mass of each element is equal to the given percent.

Therefore, the mass of  is
