How do you determine the mass needed to make a certain molarity and certain pH solution?...
How do you determine the mass needed to make a certain molarity and certain pH solution? For example, if I need to make 300 mL of 0.05 M Tris Base and 0.05 M NaCL (pH 8.2) from 2M of both, how do I do the math for that and get the grams needed of each?
Also how do you use the Henderson-Haseelbach equation to determine how much .1 M KH2PO4 to add to 100 mL of of K2HPO4 to give a pH of 7.0 (pKa = 6.86).
