Pentane is burnt to produce carbon dioxide 40% of which can be converted into carbon monoxide, how much Butane must be burnt to produce 176 grams of carbon monoxide? Correct Answer 36 grams

The balanced chemical reaction is C5H12 + 8O2 -> 5CO2 + 6H2O, Let the mass of pentane be x, => (x/72)*5*44*(40/100) = 176, => x = 36 grams.
