Question

Cu2O reacts with Cu2S to produce Cu and SO2 gas. How many moles of SO2 is produced when 0.48 mol Cu is produced in this reaction?

Answer 1

2.88moles

Step-by-step explanation:

To solve this question adequately, we need to have a balanced chemical equation

2Cu2O + Cu2S → 6Cu + SO2

From the chemical equation, we can see that the mole ratio of the sulfur oxide to the Cu is 6 to 1.

This means that if 0.48 mole is sulfur oxide is produced, then 6 of this number of moles would have been produced in the case of Cu.

Hence, to get the number of moles of copper produced, we simply multiply 0.48 by 6 to give 2.88 moles
