Answer:
0 kJ/mol.
Explanation:
Hello,
In this case, since the chemical potential can be represented in terms of the Gibbs free energy of formation:
[tex]\mu = \frac{\Delta _fG}{n}[/tex]
Thus, since the Gibbs free energy of formation of an element is zero, the chemical potential is also zero, or just 0 kJ/mol.
Best regards.
