Which of the following is true about Rex's cereal-milk mixture? A. The mass of the cereal-milk mixture is still 273 g even though the volume of the cereal grains has increased. B. The mass of the cereal-milk mixture is equal to 217 g, which is the difference in mass between the milk and cereal grains. C.
