Calcium Chloride, Dry USP Grade - How Prepare Solution?

[atreyablue]

Can someone tell me what the right percentage for making a calcium chloride solution?

(I will be adding it to 1-2 gal batches of store bought milk)

I purchased a bottle of USP grade calcium chloride dried and need to mix it up.

Also it's my understanding this has indefinite shelf life, correct me if I'm wrong.
I searched on here and can't seem to find this subject covered.

Thank you,

Eric
