Formula used
k = M(measured) / M(empirical); molecular = k × empirical
Every result substitutes your values into this relation step by step above.
Assumptions
- The measured molar mass should be within 2 % of an integer multiple of the empirical formula mass.
- Hydrate dots in the empirical input are scaled consistently.
