Its formula mass is $73.89$ $73.89$ $g \cdot m o l^{- 1}$ $g*mol^-1$ .

Explanation:

As you know this salt is commonly used to treat mania. The formula mass is simply the sum of the molar masses of the contributing atoms: i.e. $(2 \times 6.94 + 12.011 + 3 \times 15.999) \cdot g \cdot m o l^{- 1}$ $(2xx6.94+12.011+3xx15.999)*g*mol^-1$ $=$ $=$ $? ?$ $??$
