On quiz problems that say 25C, I've always thought the final answer should have 2 sig figs. I have seen some discrepancies and wanted some clarification.

If you use temperature in your calculations, then yes, it does affect sig figs. If you don't use temperature in your calculations, then it doesn't affect sig figs.

Assuming you use temperature in your calculations, it does count for sig figs because it is a measurement. In general, anything you measure that does not have 100% accuracy counts for sig figs and any exact values, like conversion factors, do not count for sig figs.

yes all values incorporated into your calculations count for sig figs

Generally, if temperature is part of the values in your calculation, yes.
