50 grams 250 grams 300 grams 550 grams
I gave my students this multiple choice question: A container is filled with 250 milliliters of water. The total mass of the container and the water is 300 grams. What is the total mass of the container and the water after being in a freezer for 2 hours?

Only one answer is correct among these 4 choices:
- 50 grams
- 250 grams
- 300 grams
- 550 grams

Could you tell me which one is correct?

300 grams
