If the solubility of sodium chloride (NaCl) is 30.6 g/100 mL of
H2O at a given temperature, how many grams of NaCl can
be dissolved in 250.0 mL of H2O?
If the solubility of glucose
(C6H12O6) is 120.3 g/100 mL of
H2O at a given temperature, how many grams of
C6H12O6 can be dissolved in
75.0 mL of H2O?
Only 0.203 mL of C6H6 will dissolve
in 100.000 mL of H2O. Assuming that the volumes are
additive, find the volume/volume percent of a saturated solution of
benzene in water
Only 35 mL of aniline (C6H5NH2)
will dissolve in 1,000 mL of H2O. Assuming that the
volumes are additive, find the volume/volume percent of a saturated
solution of aniline in water.
