To find an object's density (D), first measure its mass (m) and volume (V). Then use the following equation:

D = m/V

Densities of Common Substances

Substance Density (g/cm3)

Water (liquid) 1.00

Silver (solid) 10.50

Lead (solid) 11.35

Examine the above equation and table. Robin has a lead ball with a mass of 227 g. What is its volume?

A.

476.7 g3

B.

20 g3

C.

20 cm3

D.

11.35 g/cm3

Frederick Collier · Answer 1

C. 20 cm^3

Step-by-step explanation:

Using the equation D=m/v, you would plug in the given mass (227 g) into m and the given density of lead (11.35 g/cm^3). Solving for v=m/D, we find the answer to be 20 cm^3.

Also, you could cancel out all the answers except C because it is the only one in units of volume (1 cm^3 = 1 mL).
