Answer:
0.0025
Explanation:
3.4g of Ethanol is Dissolved in 500g of Water
(To make calculations easy, we will take 6.8g of Ethanol in 1000g of Water)
No. of Moles in 1000g of water = 55.5
No. of Moles in 6.8g of Ethanol = 0.14
Mole Fraction of Ethanol = (Moles of Ethanol)/ Total Moles in Solution
= 0.14/55.64
= 0.0025
