The number of moles of weak monoprotic acid? - Hydrazoic acid, HN3, and butyric acid, HC4H7O2, are both weak monoprotic acids. Their pKa values (at 25oC) are 4.72 and 4.82, respectively. What is [C4H7O2-] in a solution in which the stoichiometric ...
significant figures - Need to calculate the average of the following two figures, and be sure to keep significant figures.
19.5 + 20.40 = 39.9
39.9 /2 = 19.95
If the answer is 19.95, what is the answer using signi ...
