A student adds 34.2 mL of water to 72.3 mL of a 7.50 M glucose solution. (i) Will this solution be concentrated or dilute

The solution will be dilute

Explanation:

The concentration of a solution is defined as the ratio between an amount of solute (Glucose, in this case) and an amount of solvent (Water in this case).

As the student is adding some water (Solvent), the amount of solute per amount of solvent will decrease. That is, if the concentration decreases,

the solution will be dilute

your answer would be “dry”

just did the assignment and the answer was #1 +2 n
