n CO2 : = Koefisien CO2 / Koefisien C5H10 × n C5H10 = 10 / 2 × 0,2 mol = 1 mol
Mr CO2 : = Ar C + 2.Ar O = 12 + 2.16 = 44 gram/mol
Banyaknya CO2 : = n × Mr = 1 mol × 44 gram/mol = 44 gram

C5h10 +15/2 o2 -> 5co2 + 5h2o c5h10= mol=gr/mr n=14/70 n=0,2 perbandingan mol bisa dipakai manjadi perb koefisien jadi n 5co2=gr/mr 1=gr/44 jadi gr co2=44
m C5H10 = 14 gram
Ar C = 12 , O = 16 , H = 1
Ditanya : Banyaknya CO2 yang dihasilkan ?
Jawab :
Mr C5H10 :
= 5.Ar C + 10.Ar H
= 5.12 + 10.1
= 70 gram/mol
n C5H10 :
= m / Mr
= 14 gram / 70 gram/mol
= 0,2 mol
Reaksi pembakaran C5H10 :
2C5H10 + 15O2 -----> 10CO2 + 10H2O
n CO2 :
= Koefisien CO2 / Koefisien C5H10 × n C5H10
= 10 / 2 × 0,2 mol
= 1 mol
Mr CO2 :
= Ar C + 2.Ar O
= 12 + 2.16
= 44 gram/mol
Banyaknya CO2 :
= n × Mr
= 1 mol × 44 gram/mol
= 44 gram
c5h10= mol=gr/mr
n=14/70 n=0,2
perbandingan mol bisa dipakai manjadi perb koefisien jadi n 5co2=gr/mr
1=gr/44 jadi gr co2=44
