LPG has 60% propane and 40% butane: 10 litres of this mixture is burnt. Calculate the volume of carbon dioxide added to atmosphere.

\[\ce{C3H8 + 5O2 → 3CO2 + 4H2O}\]

\[\ce{2C4H10 + 13O2 → 8CO2 + 10H2O}\]

उत्तर

Ratio of propane and Butane in mixture 

= 60 : 40

= 3 : 2

Ratio in 10 litres mixture = `3/5 xx 10 and 2/5 xx 10`

= 6 lit : 4 lit

\[\ce{C3H8 + 5O2 → 3CO2 + 4H2O}\]
1 vol                       3 vol

1 volume of propane produces CO2 = 3 volumes

∴ 6 litres produces CO2 = 3 x 6

= 18 litres   ...(i)

\[\ce{2C4H10 + 13O2 → 8CO2 + 10H2O}\]
2 vol                              8 vol

2 litres of Butane produces CO2 = 8 litres

∴ 4 litres produce CO2 = `(8 xx 4)/2`

= 16 litres   ...(ii)

∴ CO2 added to atmosphere = 18 + 16

= 34 litres.
