SUMMARY
The density of a proton can be calculated using its mass of 1.67 x 10-27 kg and its modeled volume. The proton is approximated as a sphere with a diameter of 2.4 femtometers (fm), leading to a radius of 1.2 x 10-15 m. The volume is computed using the formula Volume = (4/3)πr3, resulting in a volume of 7.2 x 10-45 m3. The density is then calculated as Density = mass/volume, yielding a density of 2.31 x 1017 kg/m3.
PREREQUISITES
- Understanding of basic physics concepts, specifically density and volume calculations.
- Familiarity with the formula for the volume of a sphere: Volume = (4/3)πr3.
- Knowledge of scientific notation and unit conversions, particularly in the context of femtometers.
