Answer #1

Solution preparation,

To make 7.5 ml of 10% yeast solution

volume of yeast solution = 10 x 7.5/100

                                        = 0.75 ml

therefore,

ml of buffer needed = 7.5 - 0.75

                                = 6.75 ml

you need to prepare a buffer solution with a ph of 7.8. A lab mate tells you to use N-2- hydroxyethylpiperazine-N'-2-ethanesulfonic acid(HEPES), a sulfonic acid with a pka of 7.5. since you know that the buffer pka should be close to the desired pH, this sounds good. You make the solution according to the following recipe, which is supposed to make 600 ml of a 0.5 M solution: dissolve 0.2 moles of HEPES in 400 ml of water. add 0.1...
