What is the formula of the unknown hydrocarbon?

C2​H3​ is the empirical formula of an unknown hydrocarbon which yields 2.4 grams (g) of carbon and 0.30 g of hydrogen when analysation was done.

How do you calculate the combustion 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 much oxygen is required for combustion of 10cm3 hydrocarbon?

10cm 3 of a gaseous hydrocarbon required 20 cm 3 of oxygen for complete combustion. 10 cm 3 of carbon dioxide was produced. Calculate the molecular formula of the hydrocarbon. Hence, the molecular formula of the hydrocarbon is CH 4.

What happens when 50cm3 of hydrocarbon is burnt?

When 50cm3 of hydrocarbon y is burnt, it reacts with exactly 300cm3 of oxygen to form 200cm3 of carbon dioxide. Water is also formed in the reaction. Can you deduce the equation?

How much carbon dioxide is produced when hydrocarbons are partially burned?

Small amounts of unburned and partially burned hydrocarbons could also be present, depending on the completeness of combustion. 20cm3 of an unknown hydrocarbon burns completely in 130 cm3 oxygen to produce 80cm3 of carbon dioxide, what is the molecular formula of the unknown hydrocarbon?

How do you calculate the number of carbon atoms in hydrocarbon?

Determine the formula of the hydrocarbon. Since each carbon atom in an alkane will burn to produce one carbon dioxide molecule, then 100/20 = 5 carbon atoms must be in the alkane. So the alkane might be $\\ce{C5H12}$.
