Answer: Molarity is defined as moles of solute per liter of solution. So, find the moles of solute and divide by the liters of solution.
molar mass AlCl3 = 133g/mole
moles AlCl3 = 127 g x 1 mole/133 g = 0.955 moles
liters of solution = 400 ml x 1 liter/1000 ml = 0.400 liters
Molarity = 0.955 moles/0.400 liters = 2.39 M

Molarity of 122.5 grams of AlCl₃ in 1 Liter solution is 0.921 M.
What is molarity?
Molarity is defined as no. of moles of solute present in per liter of solution and it is represented as:
M = n/V
First we have to calculate the moles of AlCl₃ and it can be calculated as:
n = W/M, where
W = given mass of = 122.5g
M = molar mass of = 133g/mole
n = 122.5 / 133 = 0.921 moles
Now molarity in 1 liters can be calculated as:
M = 0.921/1 = 0.921M
Hence, molarity of AlCl₃ is 0.921M.
