Question

Identify the correct set-up. If 0.900 moles of carbon dioxide from, how many grams of iron would also form, given the following chemical reaction: 3CO + Fe₂O₃ → 2Fe + 3CO₂?

Answer 1

Option D. 0.9mol x 2mol Fe /3mol CO2 x 55.845g Fe /1mol Fe

Step-by-step explanation:

The balanced equation for the reaction is given below:

3CO + Fe₂O₃ → 2Fe + 3CO₂

Molar Mass of Fe = 56g/mol

From the balanced equation above,

3 moles of CO2 produced (2 mol Fe x 55.845g Fe.

Therefore, 0.9 mole of CO2 will produce = 0.9mol x 2mol Fe /3mol CO2 x 55.845g Fe /1mol Fe
