Calculating octane is a compex process, but the formula is simple (the difficulty is getting the values from the manufacturer).

Gasoline pumps typically post octane numbers as an average of two different values. Often you may see the octane rating quoted as (R+M)/2. One value is the research octane number (RON), which is determined with a test engine running at a low speed of 600 rpm. The other value is the motor octane number (MON), which is determined with a test engine running at a higher speed of 900 rpm. If, for example, a gasoline has an RON of 98 and a MON of 90, then the posted octane number would be the average of the two values or 94.

What is octane made up of?

Octane is made up of carbon and hydrogen atoms. It is a hydrocarbon compound, specifically an alkane with a chemical formula of C8H18.


Which homologous series is octane in?

Octane belongs to the homologous series of alkanes, which are saturated hydrocarbons characterized by single bonds between carbon atoms. The general formula for alkanes is CₙH₂ₙ₊₂, where "n" represents the number of carbon atoms. Octane specifically has eight carbon atoms, with the molecular formula C₈H₁₈.


What is its empirical formula isooctane?

I don't know the exact formula but, i know the density of iso-octane: 0.69 g/ml And one gallon is equal to 3,840 ml so.... all you need is the volume.


What weight of water is produced burning 19.8grams of octane?

The formula for normal octane is C8H18. Its molar mass is 114.23 g mol−1 The formula for its combustion is 2C8H18 + 25O2 --> 16CO2 + 18H2O So 1 mole of octane gives 9 moles of water. One mole of water has a mass of 18 g 19.8 g of octane is 114.23/19.8 moles so its combustions gives ((114.23/19.8) x 9 x 18 ) = 934.61 g of water


A gasoline sample contains 80percent iso octane and 20percent n-heptane.what is its octane number?

The octane number of a gasoline sample can be estimated using the formula for a blend of hydrocarbons. Isooctane has an octane rating of 100, while n-heptane has an octane rating of 0. For a mixture of 80% iso-octane and 20% n-heptane, the octane number can be calculated as follows: ( (0.8 \times 100) + (0.2 \times 0) = 80 ). Therefore, the octane number of the sample is 80.

What is the common name for octane?

The molecular formula of octane is C8H18. It doesn't really have a "symbol."The "octane" in gasoline is actually "iso-octane" or 2,2,4-trimethylpentane. It has the same molecular formula, but the atoms are arranged differently than in n-octane.
