The molarity of a solution containing 20moles of NaCl dissolved in 10 liters of water is 2 mol/L.
How do we calculate molarity?
Molarity of any solution will be calculated by using the below formula:
M = n/V, where
n = moles of solute = 20 mol
V = volume of solution or solvent = 10 L
On putting values on above equation, we get
M = 20 / 10 = 2M
Hence required molarity of NaCl is 2 M.
