A solution containing 2.8 moles of magnesium bromide is combined with a solution containing excess potassium carbonate. This chemical reaction takes place: W MgBr₂(aq) + K₂CO3(aq) → MgCO3(s) + 2KBr(aq). If the volume of the resulting solution is 1.33 liters, what's the concentration of potassium bromide? Use the periodic table.
O A. 0.24 M
OB. 2.1 M
O C 4.2 M
O D 5.6 M​
