When sugar is added to a glass of sugar solution, the molarity of the solution increases. Details about molarity can be found below, which is the third option.
Molarity is a term used to identify the amount of solute, in moles, dissolved in a solvent by volume. Molarity is expressed as moles per liter (mol/L).
However, molarity is directly proportional to the amount of solute in solution. This means that as the amount of solute increases, molarity also increases.
Therefore, when sugar is added to a glass of sugar solution, the molarity of the solution increases.
