Mole Fraction and Conversions

  What is the mole fraction of ethanol (C2H5OH) in a solution made by mixing a 20.0g sample of ethanol with 80.0g of water?

  What is the mole fraction of methanol (CH3OH) in a 92.5m aqueous solution?

Please show all work and explain each step.... It has been a while since I have taken chem and this is not my best subject.  thanks!
