Asample containing kbr (m . 119 g/mol) and kno3 (m. 101 g/mol) was analysed by using the mohr method. a 1.1250-g sample is dissolved into 200.0 ml solution (solution a).20.00-ml of solution a was titrated with 1625 ml of 0.oson agnos (m- 170) solution. report cs of kn sarion4 according to the titration data aasnannann b) calculate c% w/w of kbr it the original sample.

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?
