Molecular formula : MW : CAS :
nature : by molality mB definition of the symbols of φ m; By mole fraction x definition of the symbols of φ x. Both dimensionless quantity, a unit of SI. m φ = (μ A * - μ A) - (RTMA �mB) x φ = (μ A-μ A * ) - (RT-nxA) where : μ chemical potential; R Moore gas constant; T thermodynamic temperature; x-mole fraction; * μ k refers to the pure chemical substances potential; A MA material for the relative molecular mass.
