searching for a compound with fewer than 8 carbons seems like painful work. There are thousands of organic compounds and several compounds could have similar molar mass. I don't think this question was meant to be more confusing than it's meant to be.
Right now we are trying to establish a molecular formula, the numbers of atoms in the molecule, on the basis of information we have. This is really quite easy, certainly the next step. There are not thousands of numbers less than 7, there are only 7 of them! You know the ratio of H atoms to C atoms. On that basis what number of C atoms are possible?
Frankly after you get that you'll kick yourself. I think you'll do well then to ask yourself what was stopping you get it, it may be useful to you since you seem to be voluntarily going through old papers for revision or something. I would be interested to understand myself.
So try and answer the above question. If having tried you still can't say anything about that come back for more hints.
