\(m_S=40.\dfrac{96}{100}=38,4g\rightarrow n_S=\dfrac{38,4}{32}=1,2mol\)
\(m_C=40-38,4=1,6g\rightarrow n_C=\dfrac{1,6}{12}=\dfrac{0,4}{3}mol\)
S+O2\(\overset{t^0}{\rightarrow}\)SO2
C+O2\(\overset{t^0}{\rightarrow}\)CO2
\(n_{O_2}=n_S+n_C=1,2+\dfrac{0,4}{3}\approx1,33mol\)
\(V_{O_2}=1,33.22,4=29,792l\)
\(n_{SO_2}=n_S=1,2mol\rightarrow m_{SO_2}=1,2.64=76,8g\)
\(n_{CO_2}=n_C=\dfrac{0,4}{3}mol\rightarrow m_{CO_2}=\dfrac{0,4}{3}.44\approx5,87g\)
