Question

Consider the reaction:

3A +5B + 1C --> 2D + 1E

If you have 6 moles of reactant A and excess of B and C, how much product E would be formed? Show work so I can understand please.

Answer 1

Since B and C are in excess you don't need to take them into consideration. Using the balanced equation given we can see that the mole ratio of A:E is 3:1. Now you use that ratio and apply it. So \[6A (1E/3A) = 2E\]. Moles of A cancel leaving only moles of E left.

Answer 2

So would I multiply 6x10^23 by two and that would be my answer?

Answer 3

What units are you looking for in your answer?

If the answer is to be in moles then no 2 is the answer.

If the answer is supposed to be in atoms then yes you would multiply it by Avagodro's number.

Answer 4

the question does not specify.. just wants to know how much product. if it mentions moles in the first part then should the answer be in moles?

Answer 5

I would assume so.

Answer 6

thank you
