Na2S
Refer to the Periodic Table for Relative Atmoc Masses.
2 x Na = 2 x 23 = 46
1 x S = 1 x 32 = 32
46 + 32 = 78 The answer!!!!

If you have molecular weight how can you find equivalent weight?
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
