The sink-float method is often used to identify the type of glass material found at crime scenes by determining its density.
several different types of glass of known density are placed into solutions of varying densities. determine whether each glass
piece will sink, float, or do neither when immersed in the given solution.
glass that will sink
glass that will float
glass that will not sink or float
alkali zinc borosilicate with a density of
2.57 g/ml in a solution with a density
of 2.46 g/ml
soda borosilicate with a density of 2.27 g/ml
in a solution with a density of 2.62 g/ml
alkali strontium with a density of 2.26 g/ml in
a solution with a density of 2.34 g/ml
potash borosilicate with a density of
2.16 g/ml in a solution with a density
of 2.16 g/ml

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?
