When we are asked to find the equilibrium concentrations and are given the initial concentrations and K constant, would our equilibrium concentrations follow the significant figures of the initial concentrations or the K?
Typically, you see what value in the question has the least amount of significant figures to determine how many significant figures your answer will need to be rounded to, which means you consider both the K constant and the initial concentrations.

That's what I initially thought too but there were some problems where the k had 2 sig figs and the initial concentrations had 3. However, the answers of the equilibrium concentrations follow the sig figs of the initial (3).
I don't know if it counts for anything but my T.A. said that there is not such a huge emphasis in sig figs this quarter and the processes are much more important so there is no need to stress about it as much like last quarter.
