A chemist prepares a solution of magnesium fluoride by measuring out of magnesium fluoride into a volumetric flask and filling the flask to the mark with water. Calculate the concentration in of the chemist's magnesium fluoride solution. Be sure your answer has the correct number of significant digits.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

I'm sorry but i'm only grade

Ibelieve it is b. proton.hope my answer has you : )
