Understanding Calcium Phosphate (Ca₃(PO₄)₂)
Calcium phosphate is an inorganic compound with the chemical formula Ca₃(PO₄)₂. It is commonly found in nature as minerals like hydroxyapatite, a major component of bones and teeth. Its molar mass is the sum of the atomic masses of all the atoms in one formula unit of the compound.
Step-by-Step Calculation of Molar Mass
1. Identify the Elements and Their Atomic Masses
Calcium phosphate (Ca₃(PO₄)₂) consists of: - Calcium (Ca): Atomic mass ≈ 40.08 g/mol - Phosphorus (P): Atomic mass ≈ 30.97 g/mol - Oxygen (O): Atomic mass ≈ 16.00 g/mol
2. Break Down the Formula
The formula Ca₃(PO₄)₂ indicates: - 3 calcium atoms (Ca₃) - 2 phosphate groups (PO₄)₂, each containing 1 phosphorus atom and 4 oxygen atoms
3. Calculate the Molar Mass of Each Component
Calcium (Ca):
( 3 \times 40.08 \, \text{g/mol} = 120.24 \, \text{g/mol} )Phosphorus (P):
( 2 \times 30.97 \, \text{g/mol} = 61.94 \, \text{g/mol} )Oxygen (O):
Each phosphate group (PO₄) has 4 oxygen atoms, and there are 2 phosphate groups:
( 2 \times 4 \times 16.00 \, \text{g/mol} = 128.00 \, \text{g/mol} )
4. Sum the Molar Masses
Total molar mass of Ca₃(PO₄)₂:
( 120.24 \, \text{g/mol} + 61.94 \, \text{g/mol} + 128.00 \, \text{g/mol} = 310.18 \, \text{g/mol} )
