Embryonic stem cells are routinely cultured in a medium containing 25 mM glucose. You have ordered medium, because you had run out, but you notice that you have accidentally ordered medium without any glucose in it.

A. How much glucose powder do you weigh in?
B. How much of the stock solution are you adding to 500 mL of medium?
