Question

PLEASE HELP!!1.A student collected the following data for a fixed volume of gas: Temperature (⁰C)Pressure (mm of Hg) 10726 20750 40800 70880 100960 150??? Fill in the missing data point. Show all calculations leading to an answer.2.You are given a clear solution of KNO3. Using 3 – 4 sentences (in your own words) explain how you would determine if the solution is unsaturated, saturated or supersaturated.3.Explain why gasoline will not dissolve in water.

Answer 1

Second question

Step-by-step explanation:

First, let's remember the concepts of an unsaturated, saturated, and supersaturated solution:

- An unsaturated solution is a solution that contains less than the maximum amount of solute that is capable of being dissolved.

- A saturated solution is a solution that contains the maximum amount of solute that is capable of dissolving.

- A supersaturated solution is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature.

Answer:

In this case, for KNO3, we can say:

- If we add KNO3 (crystal) to a solution (for example, water), and it dissolves completely, it would be an unsaturated solution.

- If the crystal doesn't grow, the solution is saturated.

- If we see a lot of crystals in the solution, we're going to have a supersaturated solution.
