Đổi 4480 ml = 4,48l.
\(PTHH:CH_4+2O_2\rightarrow CO_2+H_2O\)
Ta có:
\(n_{CH4}=\frac{4,48}{22,4}=0,2\left(mol\right)\)
\(\Rightarrow n_{O2}=2n_{CH4}=0,4\left(mol\right)\)
\(\Rightarrow V_{O2}=0,4.22,4=8,96\left(l\right)\)
\(\Rightarrow V_{kk}=8,96.5=44,8\left(l\right)\)
\(PTHH:2KClO_3\rightarrow2KCl+3O_2\)
\(\Rightarrow n_{KClO3}=\frac{2}{3}n_{O2}=\frac{4}{15}\left(mol\right)\)
\(\Rightarrow m_{KClO3\left(candung\right)}=\frac{4}{15}.122,5=32,66\left(g\right)\)
