Using Rh Pen plating solution in bath plating

I hope someone can help me. I have two bottles of Rhodium pen
plating solution (each containing 1 gram of Rhodium). I would like to
use this with my rectifier in a bath solution. I have the anode etc.
However, from the research I’ve done it sounds like it should be
diluted somewhat. Does anyone know how to do this? Can I just add
distilled water? Ratios?

Thanks in advance.
