What are the theoretical moles and grams obtainable when 53.9g of ethanol is dehydrated?

Answer 1

1 mole ethanol gives you 1 mole of the dehydrated material (ethene?).
Then 53.9/molar mass ethanol gives moles.
moles ethanol = moles ethene.
grams ethene (theoretical yield) = moles x molar mass ethene = ??
