What happens to a glass of sugar solution when sugar is added to it?
the number of moles of water increases.
the number of moles of water decreases.
the molarity of the solution increases.
the molarity of the solution decreases.

The molarity of the solution increases.

Explanation:

Molarity is the measure of the concentration of the solute in the solution. In this case, the solvent is the sugar solution and the solute is the sugar.

If sugar is ADDED to the already sugary solution, then there would be more sugar. Therefore, the sugar (solute) would increase in number.

This means that the answer is the third choice: The molarity of the solution increases.

The answer would not be the first or second choice because there isn't anything in the question that implies water. It just says sugar solution.

The answer is not the last choice because the sugar concentration does not decrease after you have added more sugar to it. It increases.

c: the molarity of the solution increases

14 days is the half-life of phosphorus-32

the correct answer would be d. hope this !
