Thể tích khí \(CH_4\) nguyên chất là:
\(V_{CH_4}=2\cdot\left(100\%-5\%\right)=1,9m^3=1900l\)
\(\Rightarrow n_{CH_4}=\dfrac{1900}{22,4}=84,82mol\)
a)\(CH_4+2O_2\underrightarrow{t^o}CO_2+2H_2O\)
84,82 169,64
b)\(V_{O_2}=169,64\cdot22,4=3799,936l\)
c)\(V_{kk}=5V_{O_2}=5\cdot3799,936=18999,68l\approx19m^3\)
\(2m^3=2000dm^3=2000\left(lít\right)?\)
