Find the density in g/cm3 of a 120 cm3 piece of metal having a mass of 2 kg.
2 kg equals 2000 g.
Divide that by the volume, 120 cm^3.
To find the density, we need to divide the mass of the metal by its volume. Here's how you can calculate it:
1. Start by converting the mass from kilograms to grams. Since 1 kilogram is equal to 1000 grams, multiply the mass (2 kg) by 1000:
Mass = 2 kg * 1000 g/kg = 2000 g
2. Now, plug the values into the formula for density:
Density = Mass / Volume
Mass = 2000 g
Volume = 120 cm^3
3. Divide the mass by the volume:
Density = 2000 g / 120 cm^3 ≈ 16.7 g/cm^3
Therefore, the density of the metal is approximately 16.7 g/cm^3.
