Answer:
mass of H₂O = 54.06 g
Explanation:
balanced chemical equation
Fe₂O₃(s) + 3H₂(g) → 2Fe(s) + 3H₂O(l)
given data
moles of H₂O = 3 mol
mas of H₂O = ?
Molar mass of H₂O = 18.02 g/mol
we find the mass of H₂O by:
mass of H₂O = moles × molar mass
mass of H₂O = 3 mol × 18.02 g/mol
mass of H₂O = 54.06 g
