Calculate the density of an object that has the mass of 200.0grams and a volume 50.0mL to the right significant figures.

• 4.50 g/mL
• 4.00 g/mL
• 5.00 g/mL
• 3.00 g/mL

An irregular shaped object has a mass of 30.0 grams and when it is added to 55ml of water, the total volume of water and object is 75ml. What is the density of the object?

• 1.5 grams/ml

• 0.25 grams/ml
• 0.5 grams/ml
• 1.0 grams/ml

If you have an object with the density of 3.8g/ml and you take 1/3rd of it, what will the final density be?

• 3.0 g/ml
• 4.5 g/ml
• 2.5 g/ml
• 3.8 g/ml

What is the formula for density?

• Density = Volume / Mass
• Density = Mass / Volume
• Density = Mass + Volume
• Density = Mass - Volume

What are the units for density when the volume is measured in mL and the mass is measured in grams?

• g/L
• kg/mL
• mL/g
• g/mL

Do more dense things float or sink?

• More dense things float.
• Density has no effect on buoyancy.
• All objects float regardless of density.
• More dense things sink.
