Calculam masa de iod nereactionat:
nhexena=Cm*Vs=0,1*0,15=0,015moli
1mol.....................................127*2g
CH3-CH=CH-CH2-CH2-CH3 + I2 -> CH3-CH(I)-CH(I)-(CH2)2-CH3
0,015moli...............................x=?
x=3,81g iod nereactionat
iod reactionat: 35-3,81=31,19g iod
20g grasime................31,19g iod
100g grasime.....................yg iod
y=31,19*100/20=155,93g iod
indicele de iod: 155,93g iod/100g grasime
