Question

Calculate the mole fraction of ethyl alcohol and water when there is 95% ethyle alcohol by mass

Answer 1

Answer:

Hey mate ✌️

Explanation:

Molecular mass of C2H6O (ethanol) = 46amu

molecular mass of H2O = 18amu

no. of moles = given mass/molecular mass

therefore, no. of moles of ethyl alcohol (ethanol) = 46/(molecular mass of C2H6O)

= 46/4

= 1 moles

no.of moles of H2O=90/(molecular mass of H20)

=90/18

= 5 moles

total moles = moles of ethanol + moles of H2O

= 1+5=6 moles

mole fraction of sub.= moles of sub./total moles

mole fraction of ethanol= 1/6

=0.1666

Hope it helps ❣️❣️
