FREE Expert Solution

We´re asked to determine the formula weight of Cobalt (III) carbonate, in amu per formula unit and grams per mole.

The formula weight of a compound is based on the atomic mass of the elements that constitute it.


There are two ways to report it: AMU per formula unit, of grams per mole.

  • For grams per mole, we multiply the atomic mass of each individual element by the number of elements, then we add all the elements that constitute the compound’s formula.
