Question

If the molality of methanol in an aqueous solution is 6 then the mass percentage of methanol in the solution will be​

Answer 1

Answer:Answer: The mass percent of methanol is 13.8 %.

Explanation:

Given : Molality of methanol= 5  i.e. 5 moles of methanol are dissolved in 1 kg of solvent.

Mass of methanol=

Thus mass of solution = mass of solute + mass of solvent= 160 +1000 =1160 g

To calculate the mass percent of methanol in a given compound, we use the formula:

Mass of methanol= 160 g

Mass of solution= 1160 g

Putting values in above equation, we get:

Hence, the mass percent of methanol is 13.8 %.
