Question

What mass of carbon dioxide is produced from the complete combustion of 3.80×10−3 g of methane?

Answer 1

1.06×10−3 g

Step-by-step explanation:

The balanced equation for the complete combustion of methane is:

CH4 + 2O2 → CO2 + 2H2O

From the equation, we can see that for every one mole of methane (CH4) combusted, one mole of carbon dioxide (CO2) is produced. The molar mass of methane is 16.05 g/mol. Therefore, to calculate the mass of carbon dioxide produced, we can use the molar ratio as follows:

(3.80×10−3 g CH4) × (1 mol CO2/16.05 g CH4) × (44.01 g CO2/1 mol CO2) = 1.06×10−3 g

Answer 2

1.406 mass of carbon dioxide is produced
