Balance the following chemical equation, then answer the following question. C8H18(g)+O2(g)CO2(g)+H2O(g) How many grams of oxygen are required to react with 13.0 grams of octane (C8H18) in the combustion of octane in gasoline? Express the mass in grams to one decimal place. x Incorrect; Try Again; 2 attempts remaining In order to determine the mass of oxygen needed to react with 13.0g of octane, first convert the mass of octane to moles of octane using its molar mass. Then, apply the stoichiometric conversion factor to convert the moles of octane to moles of oxygen gas, which uses the coelficients of the balanced chemical equation. hastly, convert the moles of oxygen gas to its corresponding mass
