Two students separated a mixture of oil and water by carefully pouring the oil off the top of the mixture into another container. They used a balance to measure the mass of the mixture before it was separated and also to measure the mass of the water and the oil by themselves after they were separated. Their data is shown in the table below. Separation Data
Before Separation After Separation
Mass of Oil and Water Mass of Oil Mass of Water
16.8 grams 7.6 grams 9.2 grams

What conclusion best fits the data?
A.
The mass of a mixture is less than the sum of the masses of the parts of the mixture.
B.
The mass of a mixture is equal to the sum of the masses of the parts of the mixture.
C.
The mass of a mixture is not related to the sum of the masses of the parts of the mixture.
