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
The answer will be 8.
Edit:
Sorry! I was wrong earlier.
An octet is when there is 8 electrons in the valence shell.
I hope this helped, and please mark brainliest! :)
