What is the the degree of compactness of a substance? (The degree of consistency measured by the quantity of mass per unit volume.)

• Typography

• Density

• Geology

• Volume

Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL. The mercury used to fill the cylinder weighs 306.0 g. From this information, calculate the density of mercury.

• 27.2 g/mL

• 0.07 g/mL

• 6885 g/mL

• 13.6 g/mL

Volume is __________.

• how many atoms

• how much matter is in an object

• how  much something weighs

• how much space an object takes up

What is the formula for density?

• density = mass x volume

• density = mass ÷ volume 

• density = mass + volume

• density = mass - volume
