Hey Noh, good to see you again. Step 1: Calculate the molar mass of ethene (C_2H_4) and ethanol (C_2H_5OH). The relative atomic masses are A_r: C = 12, H = 1, O = 16. Molar mass of ethene (C_2H_4): M(C_2H_4) = (2 × 12) + (4 × 1) = 24 + 4 = 28 g/mol Molar mass of ethanol (C_2H_5OH): M(C_2H_5OH) = (2 × 12) + (5 × 1) + (1 × 16) + (1 × 1) = 24 + 5 + 16 + 1 = 46 g/mol Step 2: Convert the given mass of ethene to moles. Given mass of ethene = 1.0 kg = 1000 g. Moles of ethene = MassMolar mass = 1000 g28 g/mol Moles of ethene ≈ 35.714 mol Step 3: Determine the moles of ethanol produced. The balanced chemical equation is C_2H_4 + H_2O → C_2H_5OH. From the equation, 1 mole of ethene produces 1 mole of ethanol. Therefore, moles of ethanol produced = moles of ethene. Moles of ethanol = (1000)/(28) mol Step 4: Calculate the mass of ethanol. Mass of ethanol = Moles of ethanol × Molar mass of ethanol Mass of ethanol = ((1000)/(28) mol) × (46 g/mol) Mass of ethanol = (1000 × 46)/(28) g Mass of ethanol = (46000)/(28) g Mass of ethanol ≈ 1642.857 g Convert the mass to kilograms: Mass of ethanol = (1642.857)/(1000) kg ≈ 1.642857 kg Rounding to three significant figures: Mass of ethanol = 1.64 kg Send me the next one 📸
