Formulas and Percent Composition
This page permits you to practice/check your Mass% and formula calculations in molecules with C, H, N and O only. The page can take the following inputs:
- Input any set of mass %s, which add to 100, but do not provide a gfw. The
program will return the empirical formula.
- Input the mass %s plus the gfw and the page will return the molecular formula.
- Input the mole quantities and the program will return the mass %s and the gfw.
Additional Points:
- It is strongly recommended that you clear extra data before running a
problem. To help in this:
- Pressing "Clear 1" will clear the first row only.
- Pressing "Clear 2" will clear the second row only.
- Pressing "Clear All" clears the entire form.
- Pressing "Calculate" processes the input.
