Answer:
The correct answer is option d.
Explanation:
204 grams of sugar will dissolve in 100 grams of water at 25ºC.
At 25°C , mass of sugar soluble in 100 grams of water = 204 grams
At 25°C, mass of sugar soluble in 1 grams of water =
Maximum amount of sugar soluble in 50 grams of water at 25°C:
After mixing 102 gram in 50 grams of water solution will become saturated.
Here we have 55 grams of sugar in 50 grams of water which solution is not saturated. But in comparison to solution with 5 grams of sugar and 50 grams of water the former solution is concentrated.

The correct question is as follows: 0.500 moles of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (plz help!)
Answer: The molarity of this solution is 0.25 M.
Explanation:
Molarity is the number of moles of a substance divided by volume in liter.
As it is given that there are 0.5 moles of potassium oxide in 2.00 L of water so, the molarity of this solution is calculated as follows.
Thus, we can conclude that molarity of this solution is 0.25 M.
