# What is the Gram Formula Mass (g) of Sodium Acetate (NaCH3COO)?

Just to retire this question...the formula mass is $82.03 \cdot g \cdot m o {l}^{-} 1$...
But how did I get this figure. I looked a the Periodic Table, and that tells me that the ATOMIC masses of sodium, carbon, hydrogen, and oxygen are, $22.99 , 12.01 , 1.01 , 16.0 \cdot g \cdot m o {l}^{-} 1$ respectively.
