The gram formula mass of sodium acetate (##NaCH_3COO##) is determined using the molar masses of the individual from .
There is 1 sodium (Na) in the formula, 2 carbons (C), 3 hydrogens (H), and 2 oxygens (O).
Na’s mass from the Periodic Table is 23.0. Multiplied by the 1 atom of sodium = 23.0
C’s mass from the Periodic Table is 12.0. Multiplied by the 2 carbon atoms = 24.0
H’s mass from the Periodic Table is 1.0. Multiplied by the 3 hydrogen atoms = 3.0
O’s mass from the Periodic Table is 16.0. Multiplied by the 2 oxygen atoms = 32.0
Add all masses together to get the gram formula mass.
23.0 + 24.0 + 3.0 + 32.0 = 82.0 g
