Question

Find the empirical formula of a compound containing 17.7% hydrogen and 82.3%nitrogen

Answer 1

Given is the % of H n N
So atomic wt of H is 1
atomic wt of N is 14
Divide % of H with its atm. wt and similarly N % with its atm wt I.e. 14
You will get the relative no of atoms..
to get simplest ratio..Divide the smaller value of relative no of atoms with the two.....you will get the simplest ratio
NH3
