Liquid octane reacts with gaseous oxygen gas to produce gaseous carbon dioxide and gaseous water. If 22.6g of carbon dioxide is produced from the reaction of 48g of octane and 75.6g of oxygen gas, calculate the percent yield of carbon dioxide.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

What is the measured amount of a product obtained from a chemical reaction?

Balance the following reaction. as2s3 + 9o2 → 2as2o3 + so2
