Question

In an aqueous solution of an unknown compound mole fraction of solute is 0.4. Calculate the molality of aqueous solution

Answer 1

So the question says 1.00 molal aqueous solution, which means 1.00 moles of the solute is present in 1000 g of the solvent. Hence the answer is 0.017683. This can be rounded off to 0.0177. So, the correct answer is 0.0177.
