How do you find the molecular formula of a hydrocarbon?

Explanation:

1. Given that the density of hydrocarbon at STP is 2.504gdm3.
2. So.
3. =molar volume at STP×density at STP.
4. =22.4dm3mol×2.504gdm3≈56gmol.
5. Let the molecular formula of HC be CxHy.
6. CxHy+(x+y4)O2(g)→xCO2(g)+y2H2O(l)
7. So by this equation the stochiometric ratio of HC and the CO2 produced on combustion is.
8. 5.3mg16.6mg=5.316.6.

How do you find the molecular formula from RMM?

Divide the molar mass of the compound by the empirical formula molar mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.
