Consider the reaction 2 CO + O2 → 2 CO2 .What is the percent yield of carbon dioxide (MW = 44 g/mol) if the reaction of 10 g of carbon monoxide (MW = 28 g/mol) with

excess O2 produces 8 g of carbon dioxide? Answer in units of %.

Explanation:

Hello,

In this case, given the reaction, we can directly compute the theoretically yielded grams of carbon dioxide, considering the 2:2 molar ratio between carbon monoxide (molar mass = 28 g/mol) and carbon dioxide (molar mass = 44 g/mol) and the initial reacting grams of carbon monoxide in excess oxygen:

Thus, as only 8 g were actually yielded, we compute the percent yield:

Best regards.

it would be a gas formation
