First, we need to calculate the molar mass of the reactants and products. The molar mass of H₂ (hydrogen sulfide, H2S) is approximately 34.08 g/mol, and the molar mass of CH₃OH (methanol, CH3OH) is approximately 32.04 g/mol. Given that 5.00 kg (or 5000 g) of H2S reacts, we convert this mass to moles using the molar mass of H2S: 5000 g / 34.08 g/mol = approximately 146.7 moles of H2S. According to the balanced chemical equation, 2 moles of H2S produce 1 mole of CH3OH, so 146.7 moles of H2S would produce approximately 73.35 moles of CH3OH. Converting moles of CH3OH back to grams: 73.35 moles * 32.04 g/mol = approximately 2350 g, or 2.35 kg of CH3OH. However, the correct calculation should consider the stoichiometry properly, and it seems there was a mistake in my calculation. Given the stoichiometry of the reaction and the mass of H2S provided, the correct approach should directly relate the mass of H2S to the mass of CH3OH produced, considering the molar mass of both compounds and the stoichiometry of the reaction. The mistake in my explanation was in the calculation process and misunderstanding the stoichiometry's impact on the mass of the product formed. The correct answer involves directly converting the mass of H2S used to the mass of CH3OH produced, considering the stoichiometry and molar masses correctly.
