Answer 1

Answer #1

Number of moles of Fe = 16.3 g / 55.845 g/mol = 0.292 mole

Therefore, the actual yield of Fe = 0.292 mole

From the balanced equation we can say that

1 mole of Fe2O3 produces 2 mole of Fe so

0.247 mole of Fe2O3 will produce

= 0.247 mole of Fe2O3 *(2 mole of Fe / 1 mole of Fe2O3)

= 0.494 mole of Fe

Therefore, theoretical yield of Fe = 0.494 mole

percent yield = (actual yield / theoretical yield)*100

percent yield = (0.292 / 0.494)*100

percent yield = 59.1 %
