1 tấn = 1000000 g
\(2C+O_2\underrightarrow{t^o}2CO\)
\(m_C=\frac{1000000.90}{100}=900000\left(g\right)\)
\(n_C=\frac{900000}{12}=75000\left(mol\right)\)
\(n_{C\left(pứ\right)}=\frac{75000.85}{100}=63750\left(mol\right)\)
\(n_{CO}=n_{C\left(pứ\right)}=63750\left(mol\right)\)
\(V_{CO}=63750.22,4=1428000\left(l\right)\)
\(2C\left(63750\right)+O_2\rightarrow2CO\left(63750\right)\)
\(m_C=1000000.90\%=900000\)
\(n_C=\frac{900000}{12}=75000\)
Vì hiệu suất là 85% nên số mol C phản ứng là:
\(n_{C\left(pứ\right)}=75000.85\%=63750\)
\(\Rightarrow V_{CO}=63750.22,4=1428000\left(l\right)\)
