Mass ratio
Definition in words |
The mass of component F divided by mass of component G in system 1 Note 1: Component F ≠ Component G (≠ = “not equal to”) Note 2: Component F ∉ Component G (∉ = “is not an element of”) Note 3: The quotient of mass of component F and mass of component G is denoted “mass ratio of component B” |
