Step-by-step solution
The ideal gas equation can be expressed in various forms. In the macroscopic form involving mass density , the equation is P = RT M₀ . Thus, in (A), x represents mass density (II). In the microscopic form, the equation is P = n_v k_B T , where n_v is the number density (number of molecules per unit volume). Thus, in (B), x represents number density (I). The standard molar form is PV = nRT , where n is the number of moles. Thus, in (C), x represents the number of moles (IV). The number of moles n can be written as t
