1.3.2 Density Concept & Calculations

To calculate density you would use the following equation

• D = M/V
• M = D x V
• V = M/ D
• NONE OF THESE

If a cube has a mass of 50 grams and a volume of 10cm³, what is its density?

• 10/50 = .2 cm³/g

• 10 x 50 = 500 gcm³

• 50/10 = 5 g/cm³

• not enough information

A key is placed in a graduated cylinder with 60 cm³ of water. It makes the water level rise to 67 cm³. What is the volume of the key?

• 60 cm³

• 67 cm³

• 127 cm³

• 7 cm³

If you know the density and the mass of an object, what equation would you use to calculate its volume?

• V = D/M
• V = M/D
• V = M x D
• V = l x w x h

Frank has an eraser. It has a mass of 4g, and a volume of 2cm³. What is its density?

• 8 g/cm³
• 2 g/cm³
• 1/2 g/cm³
• 24 g/cm³

What is the volume of the rock?

• 30cm³
• 10cm³
• 40cm³
• 20cm³

What is the density of water?

• 0 g/cm³

• 1 g/cm³

• 10 g/cm³

• 100 g/cm³

The density of this material is 2 g/cm³.
There are 24 cm³  Find the total mass.

• 12 grams
• 48 grams
• 12 g/cm³
• 48 g/cm³

If you are given a cube of sugar, how could you calculate its volume?

• V = M/D
• V = MD
• V = l x w x h
• V = final water level - initial water level

Calculate the density of a sugar cube with a mass of  2.9 grams and a length of 1.5 cm, width of 1.5 cm. and height of 1.5 cm.
