Problem: What mass of carbon dioxide is produced from the complete combustion of 8.10×10−3 g of methane?Express your answer with the appropriate units.The coefficients in a balanced chemical equation provide the mole-to-mole stoichiometry among the reactants and products. The molar mass (in g/ mol) can be used as the conversion factor between moles and the mass of a substance. Thus, the balanced equation and molar masses can be used in conjunction with one another to calculate the masses involved in a reaction. Complete combustion of methaneWhen methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction isCH4(g) + O2(g) → CO2(g) + H2O(g)This type of reaction is referred to as a complete combustion reaction.

What mass of carbon dioxide is produced from the complete combustion of 8.10×10−3 g of methane?

Express your answer with the appropriate units.


The coefficients in a balanced chemical equation provide the mole-to-mole stoichiometry among the reactants and products. The molar mass (in g/ mol) can be used as the conversion factor between moles and the mass of a substance. Thus, the balanced equation and molar masses can be used in conjunction with one another to calculate the masses involved in a reaction. 


Complete combustion of methane

When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is

CH4(g) + O2(g) → CO2(g) + H2O(g)

This type of reaction is referred to as a complete combustion reaction.
