A saturated solution of NaNO3 is prepared at 60.°C using 100. grams of water. As this solution is cooled to 30.°C, NaNO3 precipitates (settles) out of the solution. The resulting
solution is saturated. Approximately how many grams of NaNO3 settled out of the original
solution?

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums?
