Question

calculate the molality of 46 g ethyl alcohol,30g isopropyl alcohol and 54 g water.​

Answer 1

Answer:

molality = no.of moles of solute / weight of solvent

weight of solvent = 0.054 kg

m of ethyl alcohol = 46 × 1

46 0.054

= 1000/54 = 18.5185 m

m of isopropyl alcohol = 30 × 1

49 0.054

= 11.337 m
