Question

Answer 1

Answer #1

Weight of the compound = 327 g

MW of the compound = 65.4 g/mole

Volume of the solution = 2500 mL = 2.5 liters

Molarity formula = moles of solute/volume in liters

No. of moles = weight/molecular weight = 327/65.4 = 5 moles

Therefore, Molarity = 5/2.5 = 2 mol/litre.

Units of molarity are moles/liter.
