Calculating Density

If you have a liquid with a density of 1.5 g/mL, how will it behave when mixed with water?

• It will float on the surface of the water.

• It will sink because it is denser than water.

• It will mix evenly with the water.

• It will evaporate immediately.

If an object has a density less than 1 g/mL, will it sink or float in water?

• It will sink.

• It will float.

• It will neither sink nor float.

• It will dissolve in water.

What are the two types of measurements that make up density?

• Mass and Volume

• Length and Width

• Time and Speed

• Temperature and Pressure

What happens to the density of an object if you increase its mass while keeping its volume the same?

• The density decreases.

• The density remains the same.

• The density increases.

• The density becomes zero.

If a block of wood has a mass of 50g and a volume of 200cm³, what is its density?

• 0.10g/cm³

• 0.25g/cm³

• 0.50g/cm³

• 1.00g/cm³

What happens to the density of an object if you increase its volume while keeping its mass the same?

• The density increases.

• The density decreases.

• The density remains the same.

• The density becomes zero.

If an object has a density of 0.8 g/mL, will it sink or float in water?

• It will sink.

• It will float.

• It will neither sink nor float.

• It will float only if the water is warm.

What is the density of a copper bar with a mass of 216g and a volume of 24cm³?

• 7g/cm³

• 8g/cm³

• 9g/cm³

• 10g/cm³

What is density?

• Density is a measure of how much mass is contained in a given volume.

• Density is the weight of an object divided by its height.

• Density is the total mass of an object regardless of its volume.

• Density is a measure of how much space an object occupies.

Calculate the density of a substance with a mass of 30g and a volume of 10mL.

• 2g/mL

• 3g/mL

• 4g/mL

• 5g/mL
