Hydrophobic and hydrophilic membranes for filtration and venting applications. One of these isomers, 2,2,4-trimethylpentane (commonly called iso-octane) is used as one of the standard values in the octane rating scale. Finding molar mass starts with units of grams per mole (g/mol). For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. Browse the list of Join Yahoo Answers and get 100 points today. Using the following equation for the combustion of octane. Name: Octane. You start by finding the molar mass of octane, C_8H_18 This is 114 grams, because there are eight moles of carbon atoms and eighteen moles of hydrogen atoms in each mole of octane molecules. Octane = C8H18 sooo( 8 X 12) + (18 x 1) = 114 grams is the molar mass. How do you find the molar mass of octane? For Your Answer, Type In A Whole Number Without Decimal Point(e.g. ΔH°rxn = -11018 kJ.
