at what temperature is the solubility or potassium nitrate equal to the solubility of sodium nitrate?

yoy have 75 grams of sodium nitrate. At what temperature will all of the solid dissolve in 100 cm3 of water?

what temperature is required to dissove 110 grams of sodium nitrate in 100 cm3 fo water?

if 20 g of sodium chloride are dissolved in 100 cm3 of water at 20 gC, is the solution saturated?

How do you know if a solution is saturated?

A maa of 30 g of potassium nitrate is dossolved in 100 cm3 of water at 100gC. How many more grams of potassium nitrate must be added to saturate the solution?

What termprature is necessaty in order to dissolve twice as much of these solids in 100 cm3 of water as can be dissolved at 20gC

a. sosium nitrate
b. potassium nitrate
c. sodium chloride

Tony--I don't have any of the tables and/or graphs you have to solve this problem. Isn't it just a matter of reading it from a table or graph?
