Density I - 7th

A student correctly determined the density of two rocks. If the volumes of the two rocks are equal, the rock with the greater density has a

• rounder shape

• smoother surface

• greater mass

• smaller size

The volume of a sample of sulfur was measured to be 5.0 cm³. What is the mass of this sample?

• 2.5 grams

• 2.0 grams

• 5.0 grams

• 10.0 grams

The data table shows three properties of six different-sized samples of quartz sand. One property of the samples is labeled X. A student used the data for mass and property X to calculate the density of each sand sample.

What property of the samples is represented by X?

• weight

• density

• volume

• temperature

The diagram shows 20.0 grams of two different materials, A and B, on a laboratory balance.

Compared to material A, material B has a different

• density

• mass

• shape

• temperature

The diagram below a rock suspended above an overflow container filled with water up to the overflow spout. A graduated cylinder is positioned next to the container to collect water that comes out of the overflow spout.

Which property of the rock can be directly determined when the rock is placed in the overflow container?

• mass

• density

• volume

• temperature

The diagram shows a tall beaker with four different liquids and their densities.

If a ball that has a density of 1.73 g/cm³ is placed in the beaker, where will the ball come to rest?

• on top of liquid A

• between liquids B and C

• between liquids C and D

• on the bottom of the beaker

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

Which of the following is a formula to find the mass of an object, when you have the measurements for density and volume?

• Mass = Density X Volume

• Mass = Density/Volume

• Mass = Volume/Density

Which of the following is a formula to find the volume of an object, when you have the measurements for density and mass?

• Volume = Mass/Density

• Volume = Density/Mass

• Volume = Density X Mass

Which of the following is the formula to find the volume of a regularly shaped object, like a cube? This method would not use water displacement.

• Volume = Length X Width

• Volume = Length X Width X Height

• Volume = Length + Width + Height

• Volume = (Volume of liquid and rock)- (Volume of liquid only)
