1. How many grams of KClO₃ could be dissolved in 100 grams of water at 75 °C? 2. How many grams of NaNO₃ could be dissolved in 500 grams of water at 20°C?

18. A supersaturated solution of KNO₃ at 50°C contains 125 g of dissolved KNO₃ per 100 g of water. If a seed crystal was added, how much solid KNO₃ would precipitate?

19. How much NaNO₃ would precipitate when a solution containing 168 g of solute in 100 g of water was cooled from 80°C to 35°C?

20. If 150 g of NaCl was added to 200 g of water at 20°C, what would happen?

I don't care which one you answer I just need help
