I am using Ware cyanotype and want to try his suggestion of adding some 40%
citric acid solution to sensitizer to allow it to work with a wider range
of papers. I'm not used to mixing this high a concentration of solid to
liquid so am looking for the correct procedure.

If I wanted to end up with 1 liter of this solution, would I start with
400gms of citric acid and add water to make 1 liter?
