Worked practice questions

The relation between universal gas constant $R$, Avogadro number $N_A$, and Boltzmann constant $k_B$ is:

  1. $R = k_B/N_A$
  2. $R = N_A k_B$
  3. $R = N_A + k_B$
  4. $R = N_A^2 k_B$
Show answer and solution

Correct answer: B. $R = N_A k_B$

$R = N_A k_B$. $R$ is per mole; $k_B$ is per molecule. Dividing $R$ by $N_A$ gives the per-molecule constant.
