Question

The volume of 50 g of a substance is 20 cm³. If the density of water is 1 g cm⁻³, will the substance float or sink?

Answer

Given:

  • Mass of the substance (M) = 50 g

  • Volume of the substance (V) = 20 cm³

  • Density of water = 1 g cm⁻³

Calculation:

\text{Density of the substance} = \frac{\text{Mass}}{\text{Volume}}
\text{Density} = \frac{50}{20}
\text{Density} = 2.5 \text{ g cm}^{-3}

Conclusion:
Since the density of the substance (2.5 g cm⁻³) is greater than the density of water (1 g cm⁻³), the substance will sink.
