Question

4. A cork has a volume 625 cm³. The density of the cork is 125 g cm3. Find the mass of the cork.​

Answer 1

Density d = 0.25 g cm-3 V= 25 cm-3 density = d=\frac{M}{V}

M=d\times V

M = 0.25\times 25

= 6.25\ g

Density (D) is a quantity defined as mass (m) per unit volume (v): D = m ÷ v. Since these three quantities are related, you can find one of them if you know the other two. This is more helpful than it sounds because density is often a known quantity that you can look up, assuming you know the composition of the material.
