I recently stumbled upon a question that I didn't really understand how to answer.
For a 0.20 M solution of potassium sulfate, K2SO4, calculate the amount, in mol, of:
a) Potassium ions, K+
b) Sulfate ions, SO42-
I first thought that you would need to do n=C x V but with no Volume given i was unsure of how to answer it
I did decide to convert 0.20M/0.20mol L-1 into g L-1 = 0.20M x 174gMol-1 which gave a result of 34.86 g L-1. This is where i am stuck, I don't know what do do from here =/ Any help is good.
Thanks again, appreciate all the effort.
