Question
Consider the following generic equation:
3A + B ---> 2C + D
2.0 mol A and 1.0 mol B react to form 1.0 mol C. What is the percent yield of this reaction?
Please help! thanks!

You need 3 mol of A for every mol of B
but you only have 2 mol A
so you only use 2/3 of a mol of B
that would yield 4/3 mol of C
but we only got 1 mol of C
100 * 1/(4/3) = 75 % yield
