Question

José performs an experiment to determine how much sugar can be dissolved in 250 milliliters (mL) of water at 25°C. He adds 50 grams (g) of sugar at a time to the water while stirring and observes the solution. After adding sugar the eleventh time (550 g), he notes that undissolved sugar has settled to the bottom of the container. He stops adding sugar and ends his experiment. In his lab write-up he concludes that the solubility of sugar in water at 25°C is 500 g per 250 mL. Is his conclusion defensible, and why or why not?
A) No, because he did not add sugar enough times.

B) Yes, because when he added more than 500 g it did not all dissolve.

C) No, because he does not know if any of the final portion of sugar dissolved.

D) Yes, because when he added the tenth portion (500 g) all of it dissolved
