How much CO2 is produced from the combustion of a tank of propane C3H8?

What is the mass of carbon dioxide produced?

a. 2.7kg

b. 9.0kg

c. 19.8kg

d. 26.9kg

Answer:

The mass of carbon dioxide produced is 26.9 kg.

When a tank of propane C3H8 is combusted, the amount of carbon dioxide produced can be calculated based on the given parameters. In this case, the tank contains 9kgs of propane and the molecular weight of propane is 44.1 g/mol.

First, we need to calculate the moles of propane present in the tank. Using the formula number of moles = given mass / molar mass, we find that there are 204.08 moles of propane.

The chemical equation for the combustion of propane shows that 1 mole of propane produces 3 moles of carbon dioxide. Therefore, 204.08 moles of propane will produce 612.24 moles of carbon dioxide.

By further calculations using the molar mass of carbon dioxide and the number of moles, we find that the mass of carbon dioxide produced is 26.9kg. This calculation is important in understanding the environmental impact of propane combustion and the resulting CO2 emissions.
