Question

calculate the mole fraction of 10g of ethanol in 90g of water tell me this answer​

Answer 1

Step-by-step explanation:

Concentration %m/m = mass of solute / mass of solution * 100%

For ethanol : 10 g ethanol / ( 10 g + 90 g) solution * 100% = 10%m/m

For water = 90 g water / ( 10 g + 90 g ) solution* 100% = 90%m/m

Answer 2

Answer:

Concentration %m/m = mass of solute / mass of solution * 100%

For ethanol : 10 g ethanol / ( 10 g + 90 g) solution * 100% = 10%m/m

For water = 90 g water / ( 10 g + 90 g ) solution* 100% = 90%m/m
