The chemical formula of the chelating agent Versence is `C_(2) H_(4) N_(2) (C_(2) H_(2) O_(2) Na)` If each mol of this compound could bind 1 mol of `Ca^(2+)`, what would be the rating of pure Versene, expressed as `mg CaCO_(3)` bound per `g`. Of chealting agent? `Ca^(2+)` is expressed in terms in terms of amount of `CaCO_(3)` it could form.
`[Mw "of vesene" = 380, Mw "of" CaCO_(3) = 100 g mol^(-1)]`

Explanation

To solve the problem, we need to determine how much calcium carbonate (CaCO₃) can be bound by 1 gram of the chelating agent Versene.

### Step-by-Step Solution:

1. **Identify the Molecular Weights**:
- The molecular weight (Mw) of Versene is given as 380 g/mol.
- The molecular weight (Mw) of CaCO₃ is given as 100 g/mol.
