Question

What volume of oxygen gas measured at 0掳c and 1atm, is needed to burn completely 1l of propane gas measured under the same condition?

Answer 1

5 L of oxygen required to burn one liter of propane at 0°C.

Explanation:

At STP any gas occupies 22.4 L volume

The balanced reaction between propane and oxygen is as follows:

Volume of = 22.4 L

Volume of = 5 22.4 L

To burn 22.4 L of propane requires 5 \times 22.4 L of oxygen.

Therefore, five liters of oxygen requires to burn one liter of propane.
