I need to find the half life time of a capacitor and the equation is above.. I know what C is but I don't know R.. is there a way to calculate R in this case?

Unfortunately you need RC to determine time. With a tiny resistance it will be smaller than with a larger resistance. Without more information, you can only determine t in terms of R.
