Formula unit mass of KCl
Dear Student
Formula unit mass is the sum of the atomic masses of all atoms present in a formula unit of a compound. It is calculated by adding the atomic masses of all the atoms present in one formula unit.
Formula unit mass of KCl = Atomic mass of K + Atomic mass of Cl
= 39 + 35.5 = 74.5 g mol-1
