A saturated solution of sodium nitrate at 70oC is cooled to 40oC.  How many grams of precipitate are formed?

Do you have solubility tables? And don't you need to know how much solution you have?

This is all the info I have DrBob222
I don' have a solubility table. It doesn't say how much solution either,huh, is this something that can be answered?

I don't think so. Doesn't it make sense to you that if we had a liter and cooled it that we would get x grams NaNO3. If we had 2L we would get 2x grams NaNO3 and if we had 10 L we would get 10x grams NaNO3. Right?

yes
