You wish to make a buffer from a 25 mM stock solution to use in your experiment 'at home.' Suppose you've been provided enough to make a stock, but you only need 2 mL at 5 mM. Solve how many mL of a 25 mM stock are needed to make 2 mL of 5 mM baking soda buffer, showing the formula you use to solve the problem.

You will be preparing a working solution of 1X using a stock solution of 100X buffer. Using the formula below, perform the calculation for preparing 250 mLs of a 1X working solution from a 100X stock solution and diH2O. Include how much of each reagent is needed to prepare the working solution. Formula: C1 * V1 = C2 * V2 Provide your answer for how much stock AND how much water to use to prep. Provide units and show work.
