To completely burn 40.4 g of propane (C₃H₈), approximately 146.56 g of oxygen (O₂) is required. This is calculated by converting grams of propane to moles, using the balanced reaction equation, and converting the moles of O₂ back to grams. Ultimately, the molar ratio indicates that for every mole of propane, 5 moles of oxygen are necessary.
