Answer:
Explanation:The final homogenous solution, after cooling it to 40°C, will contain 47 g of potassium sulfate disolved in 150 g of water, so you can calculate the amount disolved per 100 g of water in this way:
[47 g of solute / 150 g of water] * 100 g of g of water = 31.33 grams of solute in 100 g of water.
So, when you compare with the solutiblity, 15 g of solute / 100 g of water, you realize that the solution has more solute dissolved with means that it is supersaturated.
To make a saturated solution, 15 grams of potassium sulfate would dissolve in 100 g of water.

To correct her measurement to standard temperature and pressure (STP), she must <span>make a volume correction based on a higher temperature of 273 K. The answer is letter B. This is in order to correct the temperature and pressure because correcting the volume will indicate that the temperature and pressure will result to the opposite result of the volume. This is because volume is indirectly proportional with pressure and temperature.</span>
