Achemistry student adds a quantity of an unknown solid compound x to 5.00 l of distilled water at 15.° c . after 10 minutes of stirring, only a little x has dissolved. the student then drains off the solution and evaporates the water under vacuum. a precipitate is left behind. the student washes, dries and weighs the precipitate. it weighs 0.17 kg. can you calculate the solubility of x in water at 15.° c
