Using the BSA working solutions created above, how much and which concentration would you pipet into three different centrifuge tubes so you end up with 200 ug, 20 ug, and 2 ug of BSA? (Note: remember to stay within the accurate range of your pipetman.)

please show detailed work including units throughout problem

Abbreviated as mg-25.

The correct answer is:   [a]:   the "stratosphere" .

Caso4(s) < > ca+2 + so4^-2 ksp = [ca+2][so4^-2] = 2.4 x 10^-5 = [0.20][so4^-2] [so4^-2] =1.2 x 10^-4 ag2so4(s) ,> 2ag+ + so4^-2 ksp = [ag+]^2[so4^-2] = 1.5 x 10^-5 = (0.30)^2[so4^-2] [so4^-2] = 1.5 x 10^-5/0.09 = 1.7 x 10^-4 caso4 would precipitate first since it requires less so4^- to form a saturated solution.  i believe this is right, i hope it !
