    Using the relative atomic masses below, calculate the amounts required to make 200 ml of a buffer containing 10 mM KH2PO4.

    K = 39; H = 1; P = 31; O = 16

    The amounts of what? You need 1.36g of KH2PO4, and then the volume will determine the concentration, but that's a calculation that you can do in your head, so is there more to it?
