the mole fraction of ethanol in the ethanol water mixture is 0.25 . the percentage concentration of the mixture by weight of ethanol is ?

Answer:
If ethanol is 0.25, then H2O will be 0.75.
Mol wt of ethanol is 46.06g/mol,
So, 0.25 mol=11.515g of ethanol

Mol wt of H2O is 18.01528g/mol,
So, 0.75 mol=13.51g of H2O

Total wt=25.02646g
wt % of etanol is = 11.515 / 25.02646 * 100 = 46.011%
Approximately 46%
