Please help asap Above is a solubility curve for KNO3.

Solubility has nothing to do with the speed of dissolving; it's a measure of how much salt will dissolve at a given temperature.

The y-axis of the graph shows you how much KNO3 will dissolve in 100 g of water. In other words, it tells you the maximum amount of solute that will dissolve at different temperatures.

The x-axis tells you the minimum temperature needed to dissolve different amounts of KNO3 in 100 g of water.

Approximately how many grams of KNO3 will dissolve in 100 g water at 0 degrees Celsius?
