Calculate the mass per cent of calcium, phosphorus and oxygen in calcium phosphate `Ca_(3)(PO_(4))_(2)`.

Explanation

To calculate the mass percent of calcium, phosphorus, and oxygen in calcium phosphate (Ca₃(PO₄)₂), we will follow these steps:

### Step 1: Determine the Molecular Mass of Calcium Phosphate
The formula for calcium phosphate is Ca₃(PO₄)₂. We need to calculate the molecular mass by adding the atomic masses of all the atoms in the formula.

- **Calcium (Ca)**: There are 3 calcium atoms, and the atomic mass of calcium is approximately 40 g/mol.
\[
\text{Mass of Calcium} = 3 \times 40 = 120 \text{ g/mol}
