Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters). In other words:
We need the molar mass to convert mass to moles.
Molar mass MgCl2 = 95.2 g/mol
Calculate the molarity:
What is the molarity of a solution containing 55.8 g of MgCl2 dissolved in 1.00 L of solution?
