Calculate the molarity of each of the following solutions:

(Express your answer with the appropriate units.)

9.06 molmol LiNO3LiNO3 in 6.53 LL of solution.

0.595 molmol FeCl3FeCl3 in 966 mLmL of solution.

Answer 1

Answer #1

Molarity is defined as the moles of solute present in 1 Litre of solution.

To calculate the molarity, we need to divide the moles of solute by the volume of solution in liters.

In case 1 there are 9.06 moles of LiNO3 in 6.53 L of solution.

Molarity = moles of LiNO3 / volume of solution in liters = 9.06 mol / 6.53 L = 1.39 mol /L = 1.39 M

( M is the symbol of Molarity with the units of moles / liter)

In case 2, there are 0.595 moles of FeCl3 in 966 mL of solution. First we need to convert the solution volume from mL to L.

Solution volume = 966mL = 966/1000 L = 0.966L

Molarity = 0.595 mol/ 0.966 L = 0.616 mol/ L = 0.616M
