What is the molarity of a solution containing 5.035grams of FeCl3 in enough water to make 500 ml of solution?

1 answer

First, we need to calculate the number of moles of FeCl3:
moles = mass / molar mass
The molar mass of FeCl3 is 162.2 g/mol.
moles = 5.035 g / 162.2 g/mol = 0.031 moles

Next, we need to calculate the volume in liters:
500 ml = 0.5 L

Finally, we can calculate the molarity:
Molarity = moles of solute / liters of solution
Molarity = 0.031 moles / 0.5 L = 0.062 M

Therefore, the molarity of the solution is 0.062 M.
