If 1.87 g of acetic acid reacts with 2.31g of isopentyl alcohol to give 2.96g of isopentyl acetate, what is the percent yield of the reaction?
A 1.50L buffer solution is 0.250 M in HF and 0.250 in NaF. Calculate the ph of the solution after the addition of 0.0500 moles of solid NaOH. Assume no volume change upon the addition of the base. The Ka for HF is 3.5E^-4
