The equation shows that 2 moles of Mg react with 1 mole of O₂. The molar mass of Mg is approximately 24.305 g/mol. Since the question does not provide the molar mass of O₂, and it seems to be a typographical error, we'll assume a typical stoichiometric calculation. For every mole of O₂, 2 moles of Mg are needed. Without the actual molar mass of O₂, a direct calculation can't be made, but if we were to proceed with a typical reaction where 1 mole of a substance reacts with 2 moles of Mg, and assuming the substance is fully reacted by 16 g of it, we would need 2 moles of Mg, which would be 2 * 24.305 g = 48.61 g, rounded to the nearest given option, 48 g. This is a theoretical approach given the lack of specific details for O₂.
