12.7 grams of magnesium chloride is dissolved into water in a flask and set aside for an experiment. The scientist forgets about the solution and the sunlight evaporates it. She needs at least 11 grams of magnesium chloride to continue the experiment. Will she be able to recover enough magnesium chloride from the original flask to continue the experiment?
A. No, due to conservation of mass, half of the magnesium chloride will have evaporated with the water and half will remain in the flask.
B. No, the magnesium chloride was dissolved thus it evaporated with the water.
C. Yes, all 12.7 grams will be in the flask.
D. Yes, only a small portion of the magnesium chloride will have evaporated with the water.
