Question

(a) Calculate the molarity of solution prepared by dissolving 175.5 g NaCl in enough
water to form 1.0 L of brine solution.
(b) Calculate molality of solution if its density is 1.25 g /ml.
(c) Calculate the mole fraction of NaCl.

Answer 1

Answer:

Molarity = Number of moles of solute dissolved in 1 litre of the solution. Hence, if 175.5g of NaCl is dissolved, we have 3 moles/litre of the solution. Therefore, Molarity of solution = 3M
