Question

An organic compound on analysis gave 48% carbon, 4% hydrogen and 28% nitrogen . Calculate its empirical formula?

Answer 1

hey ...

ok first you convert it into no. of moles by dividing the percentage composition with the molar mass of each element respectively... then find the simple ratio by dividing the no. of moles with the least no. of moles.... that will be your empirical formula...


since I have already calculated the answer is:
C:H:N=2:2:1
