Question

What is the mole fraction of ethanol in a solution made by dissolving 29.2 g of ethanol

Answer 1

Answer:

Explanation: Moles ethanol = 21.9 g x 1 mole/46 g = o.476 moles

moles water = 53.6 g x 1 mole/18 g = 2.98 moles

total moles = 0.476 + 2.98= 3.456 moles

mol fraction ethanol = 0.476/3.456 = 0.138
