grasime + 3NaOH = CH3-(CH2)14-COONa + CH3-(CH2)16-COONa + CH3-(CH2)7-CH=CH-(CH2)7-COONa + C3H5(OH)3
solutia de NaOH : analizata : NaOH + HCl = NaCl + H2O
nNaOH = nHCl V1c1 = V2c2 cNaOH = 20·1/2 = 10 mol/l
solutia initiala de NaOH : Vs = 2 l cM = 10mol/l ⇒⇒ nNaOH = 20 moli
⇒⇒ n grasime = nNaOH/3 = 20/3 moli
grasime C57H104O6 M = 884g/mol m = 20/3 ·884 = 5893,33g
