A saturated solution of NaNO, at 70 is cooled to 30 C. When this happens, some of the solute
precipitates out of the solution because the solubility decreases at lower temperatures. How
much solute precipitates out of the solution?
(Precipitates means the dissolved salute turns back into an undissolved sold
