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.Weight MeasurementsBefore Separation After SeparationWeight of Oil and Water(ounces) Weight of Oil(ounces) Weight of Water(ounces)16.8 7.6 9.2What conclusion best fits the data? A. The weight of the mixture is less than the combined weights of the oil and water. B. The weight of the mixture is not related to the separate weights of the oil and water. C. 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.

A scientist had a mixture of water and a liquid called benzene. The mixture had a weight of 5.5 ounces. The scientist used a special process called distillation to separate the water and the benzene into two separate containers. The weight of the water alone was 4.3 ounces. This data is summarized in the table below.Weight MeasurementsBefore Separation After SeparationWeight of Water and Benzene Weight of Water Weight of Benzene5.5 ounces 4.3 ounces not measuredWhat should the scientist expect the weight of the benzene alone to be? A. 5.5 ounces B. 3.1 ounces C. 1.2 ounces D. 4.3 ounces

Julie measured out 10.5 ounces of water. Then she measured 3.5 ounces of lemon juice. She added the lemon juice to the water and stirred until they were completely mixed.What was the weight of the final mixture? A. 7.0 ounces B. 14.0 ounces C. 3.5 ounces D. 10.5 ounces

For his science fair project, Bryan is comparing slime recipes. For one batch, he weighs out 934 ounces of liquid starch and mixes it with 2 bottles of glue. For the other batch, he weighs out 734 ounces of liquid starch and mixes it with 212 bottles of glue. Both batches end up weighing the same amount.Which equation can you use to find w, the weight of a bottle of glue in ounces?9.75–2w=7.75–2.5w9.75+2w=7.75+2.5wHow much does a bottle of glue weigh?Simplify any fractions. ounces

Physics students use a spring scale to measure the weight of a piece of lead. The experiment was performed two times, one in air and the other in water. If the volume of lead is 50 cm3, what is the difference between two readings on the scale? Density of water is equal to 1000 kg/m³Group of answer choices500 N0.5 N5 N50 N
