Problem: Calculate the molarity of the following aqueous solutions.0.550 g Mg(NO3 )2 in 250.0 mL of solution

FREE Expert Solution

We’re being asked to calculate the molarity (M) of 0.550 g Mg(NO3)2 in 250.0 mL of solution. Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters). In other words:


Molarity (M) = moles of soluteLiters of solution



We first need to determine the number of moles of Mg(NO3)2. We’re given the mass of Mg(NO3)20.550 g.  We can get the moles through the following:


mass of Mg(NO3)2 (molar mass of Mg(NO3)2→ moles of Mg(NO3)2
