Find the value of Avogadro number. Given the mean value of kinetic energy of a molecule of hydrogen at 273K is `5.64xx 10^(-21) `J and `R = 8.31 J m o l^(-1) K^(-1)`.

Explanation

To find the value of Avogadro's number (N_A), we can use the relationship between the mean kinetic energy of a molecule and the ideal gas constant (R). The formula for the mean kinetic energy (KE) of a molecule is given by:

\[ KE = \frac{3}{2} \frac{RT}{N_A} \]

Where:
- \( KE \) is the mean kinetic energy per molecule,
