Answer to Question #104941 in Physical Chemistry for Joanne O Riordan

Question

Consider the combustion of 1-propanol (C3H8O):
Calculate the mass of carbon dioxide produced from 100 kg of 1-propanol.
Calculate the mass of oxygen consumed in the reaction above.

Answer 1

$C_3H_8O+4.5O_2\to3CO_2+4H_2O$

$60\ g$ Propanol produce $44\times 3=132\ g$ of $CO_2$

$100 \ Kg$ Propanol will produce $\frac{132}{60}\times100\ Kg =220\ Kg$ of $CO_2$

$60\ g$ Propanol consume $4.5\times 32=144 \ g$ of $O_2$

$100 \ Kg$ Propanol consume $\frac{144}{60}\times 100 \ Kg=240\ Kg$ of $O_2$ .
