A solution is prepared by dissolving 130 g of NaNO3 in 100 g of water at 80°C. The solution is cooled to 0°C. How many grams of compound remain in solution?

How many grams of solid are formed?

    This is pretty easy. WAht is the saturated level (mass NaOH3 per 100gwater). Look at the solubility curves to get that.

    Then, that point tells you how much is still in solution.

    The difference is how much precipated.

    do i find out what the saturated level is for 80C or 0C
