Hey, need help with the following question from pharmaceutical analytical chemistry! Thank you! Calculate the pH of a solution with a total volume of 0.5 liters after dissolving 930.1 mg of the weak acid dexketoprofen (see image below), which is an NSAID. Before adding dexketoprofen, the solution has a pH of 4.1. Assume that the addition of dexketoprofen does not affect the volume of the solution. The pka of dexketorphene is 3.9 and the dexketoprofen has a molecular weight of 254.3 g/mol. OH Dexketoprofen, pka: 3.9; molmassa: 254.3 g/mol
