Answer: 249 grams
Explanation:
The balanced chemical equation is :
[tex]C_2H_4+H_2O\rightarrow C_2H_5OH[/tex]
As water is present in excess , it is called as excess reagent and ethylene is the limiting reagent.
According to stoichiometry:
1 mole of ethylene produces = 1 mole of ethanol
Thus 5.40 mole of ethylene produces =[tex]\frac{1}{1}\times 5.40=5.40[/tex] mole of ethanol
Mass of ethanol = [tex]moles\times {\text {molar mass}}=5.40mol\times 46.07g/mol=249g[/tex]
Thus 249 g of ethanol are produced from 5.40 mol of ethylene
