Molarity is the molar concentration of the solution with respect to the moles and the volume. The molarity of the magnesium ion will be 0.339 M, and the Bromium ion will be 0.678M.
Molarity is the proportion of the moles of the solute to the volume in liters of the solution present. The compound magnesium bromide completely dissociates as:
MgBr² ⇆ Mg⁺² + 2Br⁻
The molarity of the magnesium ion will be equal to the M of the magnesium bromide and hence, will be 0.339 M.
The molarity of the bromide ions will be equal to two times the M of the magnesium bromide species and hence is 0.678 M.
Therefore, the molarity of the magnesium ion will be 0.339 M, and the Bromium ion will be 0.678M.
