Problem: Calculate each of the following quantities:Number of Mg2+ ions in each milliliter of 0.184 M magnesium bromide

FREE Expert Solution

The chemical formula for magnesium bromide is MgBr2. In water, it dissociates to form Mg2+ and Br ions.

MgBr2(aq) → Mg2+(aq) + 2 Br(aq)

From this, we can see that 1 mole of MgBr2 forms 1 mole of Mg2+. From Avogadro's number, there are 6.022 × 1023 ions in 1 mole. Recall that 1 M = 1 mol/L and 1 mL = 10–3 L.
