Answer #1

Balanced chemical reaction is:

2 Fe(OH)3 -----> Fe2O3 + 3 H2O

moles of Fe(OH)3 = (5.25 g) / (106.87 g/mol) = 0.049 mol

moles of Fe2O3 produced = (1 / 2) x (0.049 mol) = 0.0245 mol

weight of Fe2O3 produced = (0.0245 mol) x (159.69 g/mol) = 3.9 grams

moles of H2O produced = (3 / 2) x (0.049 mol) = 0.0735 mol

weight of H2O produced = (0.0735 mol) x (18.02 g/mol) = 1.32 grams
