Answer:
[Co(H₂O)₆]²⁺ = 0.361 M
Explanation:
[CoCl₂ . 6H₂O] + 2Cl⁻ → [CoCl₄]²⁻ + 6H₂O
[Co(H₂O)₆]²⁺ + 4Cl⁻ → [CoCl₄]²⁻ + 6H₂O
[CoCl₄]²⁻ = 0.361 M ∴ [Co(H₂O)₆]²⁺ = 0.361 M
The equation shows that the concentration of [Co(H₂O)₆]²⁺ should be equal to the concentration of [CoCl₄]²⁻.
MgSO₄ + Pb(NO₃)₂ = PbSO₄(s) + Mg(NO₃)₂
Mg²⁺ + SO₄²⁻ + Pb²⁺ + 2NO₃⁻ = PbSO₄ + Mg²⁺ 2NO₃⁻
Pb²⁺ + SO₄²⁻ = PbSO₄
a)32.670 + 1.2240 = 33.8904
33.8904-14.0 = 19.8904
b)12.080 × 4.050 × 0.231
=54.36 × 0.231
=12.55716
c)(3.051 × 103) ×(2.00 × 10.2)=
314.253 × 20.4 = 6410.7612
