A sample with mass 50 g and volume 10 cm^3 has density?

• A. 0.2 g/cm^3
• B. 5 g/cm^3
• C. 10 g/cm^3
• D. 50 g/cm^3

Answer: (B)

Density is mass per unit volume. With a mass of 50 g and a volume of 10 cm^3, the density is 50 g ÷ 10 cm^3 = 5 g/cm^3. This shows how tightly the material’s mass is packed into each cubic centimeter. The other numerical options would require different mass–volume relationships, so they don’t match the given measurements.
