Ready to use Rhodium Bath

Hi to all Orchidians. Could anyone tell me, should you consent me to
ask, how would I turn 2 grams of Pen, Concentrated Rhodium solution,
to make a 1 liter ready to use Bath for Rhodium plating. I was
informed through browsing here and there that due to the consistency
of the Pen concentration solution, extra amount of Sulphuric acid
should added. Could anyone specify by how much to a 2gram of Pen
Concentrate and how much distilled water should I top up? Thanks for
your continued help.

Best Regards to you all
