Solution

The correct option is C $263 m g$
Versene, $C_{2} H_{4} N_{2} (C_{2} H_{2} O_{2} N a)_{4}$ has molar mass $= 380 g$ .
1 mole versene $=$ 1 mole $C a^{2 +}$ $=$ 1 mole $C a C O_{3}$ .
$∵$ 380g versene combine with 100g $C a C O_{3}$
$∴$ 1g versene combines with $\frac{100}{380} = 0.263 g C a C O_{3}$
$∴$ mg of $C a C O_{3}$ bound per g versene $= 263$ .

Versene, a chelating agent has chemical formula C2H4N2(C2H2O2Na)4. If each mole of this compound could bind 1 mole of Ca2+, then the rating of pure versene expressed as mg of CaCO3 bound per g of chelating agent is:

The correct option is C 263 mgVersene, C2H4N2(C2H2O2Na)4 has molar mass =380g.1 mole versene = 1 mole Ca2+= 1 mole CaCO3.∵ 380g versene combine with 100g CaCO3∴ 1g versene combines with 100380=0.263gCaCO3∴ mg of CaCO3 bound per g versene =263.
