Matter Classification, Density Calculations, Volume

The mass of an object is 30 g.  The volume is 5 mL.  What is the density of this object?

• 6 g/cm
• 6 g/mL
• 6

What is the density of an object that has a volume of 30 mL and 120 grams?

• 40 mL
• 4 g/mL
• 40 g/cm3
• 4 g 3

You are given the following information: mass = 48 g; volume = 24 cm^3. What is the density of this substance? 

• 2 g/cm³
• 1,152 g/cm³
• 0.5 g/cm³
• 72 g/cm³

Round this number to the tenths place.  298.20789g/ml

• 298
• 298.2
• 298.23
• 300

What units are used to measure mass of an object?

• cm
• cm³
• g
• g/cm³

What two factors do you need to calculate density?

• matter and mass
• matter and volume
• mass and volume
• weight and volume

Which statement BEST describes the relationship between the weight and mass of an object?

• If mass increases, weight will decrease.

• Doubling mass reduces weight by half.

• An increase in mass will not affect weight.

• If mass increases, weight will increase.

What happens to the mass and weight of an object that is launched into space, where the pull of gravity is less?

• The mass decreases while the weight stays constant.

• The mass stays constant while the weight decreases.

• The mass stays constant while the weight increases.

• The mass increases while the weight decreases.

Nick is preparing a solution and needs to measure the mass of some copper sulfate. Which one of the objects should he use to measure MASS?

• Electric Scale

• Ruler

• Triple Beam Balance

• Graduated Cylinder

Jen is explaining the difference between weight and mass to her sister. In comparing the two, which of the following could Jen use to CORRECTLY describe the weight of an object?

• Weight is the same everywhere in space.

• Weight is how much matter is in an object.

• Weight is the amount of gravitational pull on an object.

• Weight is not impacted by the force of gravity.
