is the number of moles of per liter of solution.

1)Calculate the no.of moles of MgBr2 by dividing 63.0 g by the Molar mass of MgBr2. ( Molar mass of MgBr2=Molar mass or in g of Mg + 2 x MM or atomic mass in g of Br)

2)Divide the number of moles of MgBr2 ( the result in step 1) by 0.15 L(volume of solution in liters). This is the Molarity of the solution
