Ni2+, Ag+, Sr2+, and Mn2+, & with the Addition of HCl --> AgCl ppts
<span>Ni2+, Sr2+, and Mn2+, & with the Addition of H2SO4 --> SrSO4 ppts </span>
<span>Ni2+, and Mn2+, & with the Addition of NaOH --> both Mn(OH)2 & Ni(OH)2 would have ppt'd </span>
<span>but since no ppt,... </span>
<span>there was no Ni+2 or Mn+2 </span>

Answer:
[KIO₃] = 0.548 M
Explanation:
Molarity is a sort of concentration which involves moles of solute in 1L of solution.
Volume of solution 5L
Mass of solution: 587 g
Let's convert the mass to moles (mass / molar mass)
587 g / 214 g/mol = 2.74 moles
Molarity is mol/L → 2.74 mol / 5L = 0.548 M
