Leonard measures 20 grams of water into a bowl and puts it in the freezer. A day later he takes it out of the freezer and observes that it is larger than before. What is the mass of the ice?(1 point)

20 grams
21 grams
25 grams
30 grams

Yes, I am sure that the mass of the ice is 20 grams. When water freezes into ice, there is no change in the total mass.
