A student obtained the following data: Mass of beaker 25.87 g
Mass of beaker with mixture sample 28.12 g
Mass of evaporating dish 146.36 g
Mass of evaporating dish with dried salt 147.10g
Mass of beaker with dried salt ???

However, this student spills her sand sample out of the evaporating dish before weighing it. If the student believe in the Law of Conservation of Mass, what should have been the weight of the beaker with the dried sand in it?

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
