C + O = CO.
12 + 16 = 28,
1 + 4/3 = 7/3.

1 + 4/3 = 7/3.

Just add up the masses: (Since mass is conserved and we can neglect the coefficients).

C+O2=CO2.

1+4/3=7/3.

2c+o2 = 2co.
2*12+32 = 2*28.

24+32 = 56 each divided by 24 then.
1+4/3 = 7/3.

1kgc and 4/3 o2 then co is 7/3.

2C+O2 = 2CO2.
1*2+2*4/3 = 2x.
2+8/3 = 2x.
14/3 = 2x.
7/3 = x.

2C + O2 = 2CO

=12*2 =32 =2*(12+16)

= 1 =32/24 =56/24

= 1 = 4/3 =7/3

That is 1 kg of Carbon(C) and 4/3 kg of oxygen(O2)is required for producing 7/3 kg of carbon mono-oxide(CO).
