Combustion of alkanes

Exercise 1

Calculate the volume of carbon dioxide n.t.p. produced by the complete combustion of $V = 30 \; m^ 3 $ butane!

$2C_4H_{10}+13O_2\;\rightarrow\; 8CO_2+10H_2O$ $n_{butane}$ $=$ $\frac{V}{22,4}$ $=$ $\frac{30000}{22,4}$ $=$ $1339\; mol$ $2\;mol$ butane give $8\;mol\;CO_2$ $n_{CO_2}$ $=$ $4\cdot 1339$ $=$ $5356\; mol$ $V_{CO_2}=n_{CO_2}\cdot 22,4=119974 \;L $
