According to the Law of Conservation of Mass, if 88 g of carbon dioxide ( CO2
) is produced in a reaction between oxygen (O) and 24 g of carbon (C), what is the mass of dioxygen ( O2
) in the reactants?(1 point)
Responses
104 g
32 g
64 g
24 g
According to the Law of Conservation of Mass, the total mass of the reactants must be equal to the total mass of the products in a chemical reaction.
Given that 88 g of carbon dioxide (CO2) is produced, we can calculate the mass of carbon (C) in the reactants:
Mass of carbon (C) = Mass of carbon dioxide (CO2) - Mass of oxygen (O) = 88 g - ?
The mass of oxygen can be calculated by subtracting the mass of carbon from the total mass of the reactants:
Mass of oxygen (O) = Total mass of reactants - Mass of carbon (C) = 88 g + 24 g
Mass of oxygen (O) = 112 g
Therefore, the mass of dioxygen (O2) in the reactants is 112 g.
