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 weight of the mixture before it was separated. After the students had separated the mixture, they
measured the weights of the water and the oil by themselves. Their data is shown in the table below.
Before Separation
After Separation
Weight of Oil and Water Weight of Oil Weight of Water
16.8 grams
7.6 grams
9.2 grams
What conclusion best fits the data?
OA. The weight of the mixture is less than the combined weights of the oil and water.
ОВ.
The weight of the mixture is not related to the separate weights of the oil and water
OC. The weight of the mixture is equal to the combined weights of the oil and water.
D. The weight of the mixture is greater than the combined weights of the oil and water,
