Final answer:
The chemical potential of an ideal gas can be calculated using the partial pressure formula P = nRT/V.
Step-by-step explanation:
The chemical potential for an ideal gas can be expressed in terms of partial pressure using the ideal gas law equation PV = nRT, where P is pressure, V is volume, n is the amount of gas in moles, T is the temperature in Kelvin, and R is the ideal gas constant. Dividing both sides of the equation by V gives us the partial pressure formula P = nRT/V. Therefore, the correct option is b) μ = P/RT.
