# What is the empirical formula of a hydrocarbon?

###### Wiki User

The empirical formula of a hydrocarbon is the simplest ratio of carbon and hydrogen atoms present in a molecule. For instance, ethane - C2H6 - is the molecular formula, but CH3 is its empirical formula.

### How do you do the empirical formula?

The empirical formula is a bit like the lowest common multiple in math. Let us take C6H1206 which is glucose. By inspection it can be seen all the subscripts can be divided by 6 to yield CH2O and that is the empirical formula. If we took the hydrocarbon C6H12 which is cyclohexane, the empirical formula would be CH2 as the 6 and 12 subscripts can be divided by 6 to yield 1 and 2. etc.

### What is the empirical formula of a hydrocarbon with 85.7 mass carbon?

12.000*n + 1.008*(2n+2) = 85.7 (CnH(2n+2) ) gives n = 6. So this hydrocarbon is C6H14, hexane

### How are the empirical and molecular formulas for a compound related?

A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.

### How do you find the empirical formula for the burning of an unknown hydrocarbon when you aren't given the amount of CO2 produced?

calculate the number of moles of carbon and of the other and by number of moles you can proceed further. the next step is that you divide by the smallest ratio. hence obtaining your empirical formula.
