Answer:
The formula mass of any compound is described in units of amu.
Step-by-step explanation:
Molecular formula is the actual number of atoms of each element in the compound.
The mass of one molecule of the compound is known as formula mass. Thus, the unit of formula mass is amu.
For example, sodium chloride has a molecular formula of NaCl. The formula mass of NaCl is 58.44 amu.
Thus, the formula mass of any compound is described in units of amu.
