Witrynamoles of octane = mass / molar mass = 58 g / 114.23 g/mol = 0.508 mol. From the balanced equation in part a, we can see that the mole ratio between octane and carbon dioxide is 2:16, which simplifies to 1:8. This means that for every 1 mole of octane burned, 8 moles of carbon dioxide are produced. Therefore, the amount of CO2 … Witryna2 sie 2015 · Formula Mass: The formula mass (formula weight) of a molecule is the sum of the atomic weights of the atoms in its empirical formula. Molar Mass: Molar mass is the mass in grams of 1 mol of substance (The number of particles in a mole is equal to 6.022 * 1023). Use Formula mass: Formula mass is calculated for chemical compounds.
