Density Quest

How do you calculate the mass of a substance when given the density and volume?

• Mass = Density x Volume.

• Mass = 0 kg.

• Mass = Density/

  volume

• Mass = Density + Volume

Calculate the Density.

• Density = Volume+Mass.

• Density = Volume/Mass.

• Density = Mass/Volume.

• Density = Mass - Volume.

Calculate the Volume.

• Volume = length+width+height

• Volume = Area × Height.

• Volume = Base × Height.

• Volume = length x width x height

A solid: Volume = 7,000 cm³, Density = 0.70 g/cm³. Calculate the Mass.

• Mass = 4900 g

• Mass = 3500 g

• Mass = 7000 g

• Mass = 6300 g

Calculate the Volume.

• Volume = ________.

• Area = ________.

• Surface Area = ________.

• Perimeter = ________.

Most woods float on water because their density is lower than that of water.

• They are less dense than water.

• They are more dense than water.

• They absorb water and swell.

• They are made of impermeable material.

The effect of heating on a substance’s density is that it decreases due to expansion. Which of the following best explains this phenomenon?

• It increases because particles move closer together.

• It decreases as the substance expands, leading to a decrease in density.

• It remains unchanged as heating does not affect density.

• It varies unpredictably without a clear trend.

Based on the following densities and what you know about the range of densities, state whether each substance below is most likely a solid, liquid or gas: a. 0.0025 g/mL
