When determining how many sig figs to include in our end values, do we factor in the sig figs of given K values too? For instance, if you want to find the concentration of H2 and have the concentrations of I2 and HI up to 3 sig figs, but your given K value only has 2, would you round the value of [H2] to 2 or 3 sig figs?
Thank you!

Re: Kc sig figs
I'm not entirely sure but I think for sig figs you just use the least given amount, and it doesn't really matter where it comes from unless otherwise stated.

Re: Kc sig figs
For log sig figs, you take the number of sig figs from the number you log and have that many sig figs after the decimal point of your answer (e.g. log(3.800) = 0.5798).
