According to the Law of Conservation of Mass, if 98 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 32 g 32 g 24 g 24 g 64 g 64 g 74 g
The mass of oxygen in the carbon dioxide molecule is 2 * 16 g = 32 g.
Therefore, the mass of dioxygen (O2) in the reactants is 32 g.
