the temperature of the oven the mass of the frosting the height of the layers the volume of the oil
I gave my students this multiple choice question: Jennifer and Mark prepared a layer cake using oil and water. After the cake baked in the oven, they added frosting. Which property could be measured with a balance?

Only one answer is correct among these 4 choices:
- the temperature of the oven
- the mass of the frosting
- the height of the layers
- the volume of the oil

Could you tell me which one is correct?

the mass of the frosting
