Molecular formula from empirical formula (Molar mass of compound = integer × empirical formula mass; k = M_substance / M_empirical)
jee-mainjee-advancedneet-ug
Molar mass of compound = integer × empirical formula mass; k = M_substance / M_empirical
What each symbol means
| Symbol | What it stands for |
|---|---|
| k | Positive integer multiplier |
| M_empirical | Mass of one empirical formula unit |
| M_molecular | Experimentally measured molar mass (g/mol) |
When to use this
M_substance is for the actual molecular species; k must be whole within experimental error.
