Question

.033597 grams of hydrogen is combined with 1.000grams of of carbon . calculate the atomic mass of hydrogen

Answer 1

lets think. It could be CH4, or C2H4 , or C6H6, or octane, C8H18.

Now the ratios of moles of carbon and hydrogen are different in each.
Looking at C8H18., the moles of H are 18/8 moles of C

Carbon moles: 1/atomicmassC

Hydrogen: .033597/atomicmassH

Hydrogen moles also equal 18/8 moles C
so 18/8 * 1/atomicmassC=.0033597/AtomicmassH

solving for atomic mass H, then

atomic massH= .0033597*atomicmassC*8/18

that works out to about...0.018. Well, that is certainly not the compound.

So I suspect you need to know which compound was formed.

Answer 2

I think something is amiss in this problem. Let's go the other way.
mols C = 1/12 = 0.083333
mols H = 0.033597/1.00794 = 0.03333
ratio is C2.48 to H1.00 which rounds to C5H2 and this is an unlikely hydrocarbon. So I don't think all of the looking in the world will help.
