The answer would be 1952.5 grams of potassium sulfate solution. The way to get the answer is to use the equation, 617/x = 31.6%/1 and then cross multiply to get 31.6%x= 617grams and then 0.316x=617 grams so then x = 617/0.316= 1952.5 grams.
Answer:
The hypothesis becomes a theory if the results support it is answer.

Answer:
In a solution the solvent is the liquid that the solute is added to.
Explanation:
Solute + Solvent = Solution.
For example: An aqueous solution of 10 g of NaCl in 100 g of water
NaCl → solute → what you dissolved
H₂O → solvent → where you dissolve
Answer:
Explanation:
Evaporation is inhibited by high humidity. Low humidity is as result of hotter temperatures that is temperature when the cup of water is under the sun and vice versa for high humidity.
Relative humidity defined as the amount of water vapor in the surrounding air compared with the maximum possible. At its maximum which is termed saturation, relative humidity is 100% and evaporation is inhibited.
The amount of water vapor the air can hold depends on its temperature. Relative humidity rises at low temperatures for example in an air conditioned environment. As the air temperature declines, sometimes reaching the dew point relative humidity is 100%, and fog may result from the condensation of water droplets if they are small enough to stay in suspension.
Drying is more effective with hot air rather than cold air, because hot air can hold more water vapor. The capacity of air to hold water vapor is based on vapor pressure of water. The liquid and solid phases are continuously giving off vapor because some of the molecules have high enough speeds to enter the gas phase.
Therefore, a cup of water placed in the sun will have a reduced water level compared to that in an air conditioned room.
2KClO₃ = 2KCl + 3O₂
n(KClO₃)=2 mol
n(O₂)=3/2 *n(KClO₃)
n(O₂)=1.5 *2 mol = 3 mol
3 moles of oxygen are produced
