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

To determine whether the substance will float or sink in water, we need to compare the density of the substance with the density of water.

Given:
– Mass of the substance = 50 g
– Volume of the substance = 20 cm³
– Density of water = 1 g/cm³

The density of a substance is calculated using the formula: Density = Mass / Volume

For the substance:
Density = Mass / Volume = 50 g / 20 cm³ = 2.5 g/cm³

Comparing the density of the substance (2.5 g/cm³) with the density of water (1 g/cm³):
– The density of the substance (2.5 g/cm³) is greater than the density of water (1 g/cm³).

Since the density of the substance is greater than the density of water, the substance will sink in water.
