Molar Mass Calculator
What is the molar mass of Ca3(PO4)2?
Answer
M(Ca3(PO4)2) =
310.174 g/mol
Atomic weights: IUPAC standard values (CIAAW, 2024).
Ca3(PO4)2 = 3 Ca + 2 × (P + 4 O) → Ca 3, P 2, O 8
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Cacalcium | 3 | 40.078 | 120.234 w ≈ 38.76% | ≈ 38.76% |
| Pphosphorus | 2 | 30.974 | 61.948 w ≈ 19.97% | ≈ 19.97% |
| Ooxygen | 8 | 15.999 | 127.992 w ≈ 41.26% | ≈ 41.26% |
| Σ = 310.174 g/mol w = 100% | 100% | |||
Each fraction is rounded on its own, so the printed ones add up to 99.99%; unrounded, they make exactly 100%.
