Question

A reaction vessel contains 8.900 g of CO and 8.900 g of O₂. How many grams of CO₂ could be produced according to the following reaction?

Answer 1

You did not provide the equation, so here it is:

2CO + O₂ ==> 2CO₂ ... balanced equation

Let us see if either reactant is limiting:

mols CO = 8.900 g CO x 1 mol CO / 28 g = 0.3179 mols

mols O₂ = 8.900 g O₂ x 1 mol O₂ / 32 g = 0.2781 mols

Based on the mole ratio of 2 mol CO : 1 mol O₂, the CO would be limiting as there is not twice as many mols.

Theoretical yield is determined by the limiting reactant:

yield = 0.3179 mols CO x 2 mol CO₂ / 2 mol CO x 44 g CO₂ / mol CO₂ = 13.99 g CO₂
