### Percentages Sig Figs?

If the question is asking for percentages (ex. Percentage composition of a molecule) do we always provide up to two decimal places (ex. ##.##%) ?

Do the sig figs normally, so if you need 4 sig figs then it would be xx.xx%

You would just put as many sigfigs as are provided in the question.

Do as you typically would so, for example, if you are given the following numbers
544.60
6.005
0.00343

Multiplying or dividing using these numbers results in three sig. figs because
544.60 --> 5 sig.figs
6.005 --> 4 sig.figs
0.00343 --> 3 sig.figs

Your answer would have to be XX.X % with only 3 sig.figs.

So for your final answer to any problem, you're only supposed to use the least amount of sig figs as were provided in the problem? Like if the problem mentions numbers with 3, 4, and 5 sig figs, our answer only needs to have 3 sig figs?

Yes, you always base it off of the lowest amount of sig figs that were given in the problem.
