LaToya is making hot chocolate.  She pours the hot chocolate powder into a glass of milk, mixes it, and then heats it up in the microwave.  LaToya claims that since she can no longer see the powder after it has been mixed, it must no longer be there.  Which of the following would not support LaToya’s claim, and instead, show that the powder is still in the mixture?

• The weight of the powder plus the weight of the milk is less than the weight of the mixture.

• The weight of the powder plus the weight of the milk is more than the weight of the mixture.

• The weight of the milk is equal to the weight of the mixture.

• The weight of the powder plus the weight of milk is equal to the weight of the mixture.
