Answer:
Answer: 53 g/eq
An equivalent weight of a solution is defined as the molecular weight of the solute divided by the valence of the solute. Equivalent weight is used for predicting the mass of a substance that reacts with one atom of hydrogen in an acid-base analysis like in titration.
The salt Na2CO3 ionizes to produce 2Na+ and CO3-2. So the charge on both ions is 2.
Since sodium carbonate contains two atoms sodium, one atom of carbon and three atoms of oxygen. The molecular weight would be
