Web24 feb. 2024 · n H2O = 3.5 * 2 = 7 mol Since the question asked for the number of grams of water that will be produced, we need to convert this molar value into mass. Each mole of water has two moles of hydrogen and one mole of oxygen. The molecular weight of water is: MW H2O = 2 * MW H2 + MW O2 = 2 * 1.01 g/mol + 16.00 g/mol = 18.02 g/mol WebCorrect option is D) The molar mass of water is 18 g/mol. 12.0 g of water corresponds to 1812=0.67 moles. 1 mole of water contains 6.023×10 23 molecules of water or 2×6.023×10 23=12.046×10 23 atoms of hydrogen. Hence, 12 g of water contains 0.67×12.046×10 23=6.023×10 23=8.0×10 23 hydrogen atoms. Was this answer helpful? …
