Explanation / Answer

Mass of eugenol in clove is 17/100 (w/w) i.e 100 gms of clove oil ----- 17 gms of clove oil/eugenol

30 gms of clove --------- ? 17x30/100 = 5.1 gms

Theoritical yield = 5.1 gms

Actual yield = mass of clove oil = 1.2 gms

percent yield (percent weight of clove oil) = (actual yield/theoritical yield ) x 100 = (1.2/5.1) x100 = 23.53%
