Nitroglycerine contains 60% as many carbon atomas as hydrogen atoms; three times as many oxygeen atoms as nitrogen atoms; and the same number of carbon and nitrogen atoms. The number of moles of nitroglycerine in 1 g is 0.0041. What is the molecular formula of nitroglycerine?
This is oooberly confusing! Where to start... ?

Molecular weight = 1/0.0041=244 g/mol. The actual molecular weight is 1/0.0044=227 g/mol. Probably a mistake in the problem...
Reducing the answers to algebreic form:
C=0.6H
C=N
3N=O
Use the lowest integers that will provide a solution to C=0.6H, or C=3 and H=5. The rest should be easy.
