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

    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).
