Question

Fe2o3(s)+3h2(g)→2fe(s)+3h2o(l) Calculate the mass of H2O

Answer 1

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
