If you dissolve 3.5 moles of cacl2 in solution how many moles of ca2+ ions and cl- ions will there be in the solution

Balanced chemical reaction (dissociation) : CaCl₂(aq)  → Ca²⁺(aq) + 2Cl⁻(aq).
n(CaCl₂) = 3,5 mol.
From chemical reaction: n(CaCl₂) : n(Ca²⁺) = 1 : 1.
n(Ca²⁺) = 3,5 mol.
From chemical reaction: n(CaCl₂) : n(Cl⁻) = 1 : 2.
n(Cl⁻) = 2 · 3,5 mol.
n(Cl⁻) =  7 mol.
Calcium chloride is salt that completely dissociate in water on calcium cations and chlorine anions.

The answer options is d

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer
