Question

calculate the mole fraction of ethanol and water in a solution in which 46 gram of Ethanol alcohol and 90% of water have been mixed​

Answer 1

Explanation

hope it helps .......

Answer 2

Explanation:

mole fraction = moles of ethanol/ moles of ethanol + moles of water

moles of ethanol = 46g (given mass )/ 46g( molar mass )=1

moles of water= 90g / 18 g =5

:: mole fraction = 1 / 6
