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.

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

closing stock calculation formula? closing stock calculation formula? closing stock calculation formula? yes how can i do the closing stock calculation?
absolutely....you can mix any octane with any other 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.
The chemical formula of octane is C8H18.

Octane is a hydrocarbon compound with the chemical formula C8H18. It is a component of gasoline and is used as a reference standard to measure the performance of fuels in internal combustion engines. Higher octane ratings indicate greater resistance to engine knocking or pinging.
