5. How many liters of propane (C_(3)H_(8)) are needed to react with 15.2 lited of oxygen at STP in order to produce water and carbon dioxide? 1C_(3)H_(8)+5O_(2)arrow 4H_(2)O+3CO_(2)

## Step 1: The balanced chemical equation for the reaction is given as: This equation tells us that 1 liter of propane reacts with 5 liters of oxygen to produce water and carbon dioxide.## Step 2:We are given that 15.2 liters of oxygen are available. We need to find out how many liters of propane are needed to react with this amount of oxygen.## Step 3:We can set up a proportion to solve for the unknown quantity of propane. The proportion is set up as follows: ## Step 4:Cross-multiply and solve for :
