What is the percentage yield when 7 g of ethene produces 6 g of ethanol?

M_r(ethene) = 28 and M_r(ethanol) = 46

C₂H₄(g) + H₂O(g) → C₂H₅OH(g)

A.     \(\frac{{6 \times 7 \times 100}}{{28 \times 46}}\)

B.     \(\frac{{6 \times 46 \times 100}}{{7 \times 28}}\)

C.     \(\frac{{6 \times 28}}{{7 \times 46 \times 100}}\)

D.     \(\frac{{6 \times 28 \times 100}}{{7 \times 46}}\)

D
