To find Molecular formula
- Find empircal formula
- Find the molar mass of gas
- Find Molar mass of empirical formula
- Divide the amu (g/mol) by the molar mass
- Multiply by the subscripts.
- (Empirical Formula)_x=Molecular Mass of elements or gas
- Solve for x and mulitply x by the subscripts of Empirical Formula
