• Spectroscopy

What is the relative density of steel compared to water?

• 7.8

• 0.5

• 1.0

• 2.5

What is the first step in determining the density of a material according to the response card?

• Drop the material into a test tube

• Weigh the material

• Use the formula density = mass/volume

• Read the volume from the tube

How is the volume of the material determined in the process described?

• By measuring the material directly

• By using a ruler

• By observing the rise in water level in a test tube

• By calculating mass/volume

What formula is used to calculate the density of the material?

• density = volume/mass

• density = mass/volume

• density = mass x volume

• density = mass + volume
