Question

A solution of ethanol in water is 1.54molal. how many grams of it are there in 2500g of the solvent

Answer 1

Answer:

Hope this helps you........

Molality = no.of moles of solute / mass of solvent *1000

Molality= mass of solute / molar mass /mass of solvent * 1000

1.54=mass of ethanol/ 46.06* 100/25

1.54*46.06*25/100=mass of ethanol

=17.73g

Answer 2
