Potassium Oxalate

I have found a number of directions for making potassium oxalate from
potassium carbonate and oxalic acid. The directions seem pretty
straight forward and the mixing does not appear to pose any danger.
However, I am confused about the percentage solution that is derived
from the mixtures.

So, assuming that I want to make a gallon of a 25% solution of
potassium oxalate for Pt/Pd printing, what amount of potassium
carbonate and oxalic acid should I start with?
