Gasohol is a fuel containing ethanol that burns in the presence of oxygen to give carbon dioxide and water as follows: C2H5(OH) + 3O2 ----> 2CO2 + 3H2O. (a) How many moles of O2 are needed to completely react with 4 moles of gasohol?..... (b) If a car produces 88g of CO2, how many grams of O2 are used up in the reaction?..... (c) If you add 125g of gasohol to your gas, how many grams of CO2 and H2O can be produced?
