C+O2 = CO2.

Molecular mass of C = 12.

Molecular mass of O = 16.

So, taking in same ratio.

12 kg of C+2*16 kg of O = 12+16*2 = 44 kg of CO2.

Hence, 12 kg of C will give 44 kg of CO2.

So, 1 kg of C will give = 44/12 kg of CO2.

= 11/3 answer.

c+o2 = co2.

12+32= 44.

1 kg of c prod 12.

12 kg of co2 prod 44.

1 kg 44/12 = 11/3.

Why dividing through out by 12?

C+O2 = CO2.

12/12+32/12 = 44/12.

1+8/3 = 11/3.

11/3 = 11/3.

C+O2 = CO2.
12/12+16/12 = 44/12.
1+4/3 = 11/3.
