Recall that the empirical formula is the simplest whole-number ratio of elements in a compound. The molecular formula is related to the empirical formula based on the molar mass.
But, since only the molar mass of the compound and mass ratio of C and H are given, we need to use mathematical techniques to:
A compound of molar mass 177 g/mol contains only carbon, hydrogen, bromine, and oxygen. Analysis reveals that the compound contains 8 times as much carbon as hydrogen by mass.
Find the molecular formula.
