What mass of carbon dioxide (in kg) is produced upon the complete combustion of 18.9 l of propane (approximate contents of one 5-gallon tank)? assume that the density of the liquid propane in the tank is 0.621 g/ml. (hint: begin by writing a balanced equation for the combustion reaction.)

The 35.1 kg of carbon dioxide produced on combustion of 18.9 Liters of propane.

Given:

18.9 Liters of liquid propane with a density of 0.621 g/mL

To find:

The mass of carbon dioxide gas produced on combustion of 18.9 L of propane.

Solution:

The mass of propane = m

The volume of the propane = v = 18.9 L

The density of the liquid propane = d = 0.621 g/mL

The mass of propane combusted = 11,736.9 g

The chemical reaction of combustion of propane

The molar mass of propane = 44.1 g/mol

Moles of propane :

According to the reaction, 1 mole of propane gives 3 moles of carbon dioxide gas, then 266.143 moles of propane will give:

Mass of 798.429 moles of carbon dioxide gas:

The 35.1 kg of carbon dioxide produced on combustion of 18.9 Liters of propane.
