The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction. This means that the mass of the reactants should equal the mass of the products.
In this scenario, you have:
- Mass of carbon (C) = 24 g
- Mass of carbon dioxide (CO2) produced = 88 g
To find the mass of dioxygen (O2) in the reactants, you can use the equation:
Mass of reactants = Mass of products
The mass of the reactants (C and O2) is equal to the mass of carbon dioxide produced plus any other products formed (in this case, there appear to be no other products).
Mass of reactants = mass of carbon + mass of dioxygen
So,
mass of dioxygen = mass of carbon dioxide - mass of carbon mass of dioxygen = 88 g - 24 g = 64 g
Thus, the mass of dioxygen (O2) in the reactants is 64 g.
