Question
Calculate the expected concentrations of vitamin B6 and caffeine in the stock solution assuming
exactly 0.0506 g of pyridoxine hydrochloride (vitamin B6) and 0.1253 g of caffeine are dissolved
in a 100 mL volumetric flask.

mols B6 = grams B6/molar mass B6 =?
Then M B6 = mols B6/L soln = mols B6/0.1L = ?
Do same for caffeine.
Note: I assume you want concn in molarity; however, not that you could do it in g/L, M, m, N, etc.
