Sig figs for percent yield

Postby AlyssaYeh_1B » Fri Oct 04, 2019 7:12 pm

In a question, say it asks me to calculate percent yield of some compound. The given sig fig is 1. If my answer is something like 56%, would I have to round it to 60% to maintain that sig fig of 1? Sig figs in the answer should match the given ones right?

Yes. Your answer should have the same number of sig figs as the value given in the question with the smallest amount of sig figs!

Yes. Calculating percent yield includes division and the rules for multiplication and division is that you use as many sig figs as the number in the problem with the fewest number of sig figs (the least precise number).
