Answer

Explanation:

Step1: Identify the masses

Mass of sugar = 15 grams, mass of water = 300 grams.

Step2: Use mass - conservation principle

Total mass of mixture = mass of sugar+mass of water. Total mass = $15 + 300$.

Step3: Calculate the total mass

$15+300=315$ grams.

Answer:

D. 315 grams
