HELP PLEASE!! 1.

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 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 if KNO3 in 100g of water.

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

Approximately what is the minimum temperature needed to dissolve 10g of KNO3 in 100G of H20?

Type in the number only; no units. Round your answer to the nearest whole number.

Imagine that you have 100g of water.

You start dissolving KNO3 in the water and you find that after you’ve dissolved about 55g of KNO3 you can’t dissolve any more; it just sinks to the bottom.

Approximately what is the temperature of water?
