Molar Mass Calculator
What is the molar mass of Li2CO3?
Answer
M(Li2CO3) ≈
73.89 g/mol
Atomic weights: IUPAC standard values (CIAAW, 2024); the sum is rounded to the decimal places of the least precise one — Li: 6.94.
| Element | Atoms, n | Atomic weight, A | n × A, g/mol Mass fraction, w | |
|---|---|---|---|---|
| Lilithium | 2 | 6.94 | 13.88 w ≈ 18.79% | ≈ 18.79% |
| Ccarbon | 1 | 12.011 | 12.011 w ≈ 16.26% | ≈ 16.26% |
| Ooxygen | 3 | 15.999 | 47.997 w ≈ 64.96% | ≈ 64.96% |
| Σ = 73.888 ≈ 73.89 g/mol w = 100% | 100% | |||
Each fraction is rounded on its own, so the printed ones add up to 100.01%; unrounded, they make exactly 100%.
