Question

Plzzz guys answer this question urgently....
A chemical compound has the following chemical composition C=19.5%,Fe=15.2%,N=22.8%,K=42.5%
Calculate the empirical formula of the compound. What will be its molecular formula if the molecular mass of the compound is 368?

Answer 1

first you converted it into gram
then we finded the no of moles of each atom
then you compare ratio of atom
by this method you find empirical formula
then we calculate the molar mass of emperical formula
then you divided by molecular mass/empirical mass
