How much carbon dioxide can you get if you burn 3.2 g of methane?

How much carbon dioxide can you get if you burn 3.2 g of methane? Determine the volume that will be occupied by carbon dioxide formed in this reaction under normal conditions.

To solve the problem, we write down the reaction equation:
CH4 + 2O2 = CO2 + 2H2O – methane combustion reaction, carbon dioxide is released;
M (CH4) = 16 g / mol;
M (CO2) = 44 g / mol;
Let us calculate the amount of moles of methane if the mass is known:
Y (CH4) = m / M = 32/16 = 0.2 mol;
Let’s make the proportion:
0.2 mol (CH4) – X mol (CO2);
-1 mol -1 mol hence, X mol (CH4) = 0.2 * 1/1 = 0.2 mol;
Let’s determine the volume of carbon dioxide:
V (CO2) = 0.2 * 22.4 = 4.48 liters.
Answer: The volume of carbon dioxide is 4.48 liters.
