Chapter 2, Problem 27E

Interpretation Introduction

Interpretation: The densities of a hydrogen nucleus and a hydrogen atom by using the mass of the proton, the mass of the electron, and the sizes of the nucleus and the atom are to be calculated.

Concept introduction: Density is a ratio relating to the mass of a substance to its volume. It is symbolized by using the symbol $\rho$ and is mathematically expressed by the formula which is as follows;

  $\text{Density}\left(\rho \right)=\frac{\text{Mass}\left(m\right)}{\text{Volume}\left(V\right)}$
