The molar mass of a compound is directly related to its composition. The molar mass is the sum of the atomic masses of all the elements in the compound. The composition of a compound refers to the types and amounts of elements present in it. Therefore, the molar mass provides information about the composition of a compound by indicating the relative amounts of each element present.
