\(C\left(1,8\right)+O_2\left(1,8\right)\rightarrow CO_2\left(1,8\right)\)
\(n_{C\left(pứ\right)}=\frac{24}{12}.90\%=1,8\left(mol\right)\)
\(\Rightarrow m_{CO_2}=1,8.44=79,2\left(g\right)\)
\(\Rightarrow m_{O_2}=1,8.32=57,6\left(g\right)\)
PTHH: \(C+O_2\underrightarrow{t^o}CO_2\)
\(n_{C\left(lt\right)}=\dfrac{24}{12}=2\left(mol\right)\)
\(n_{C\left(pứ\right)}=\dfrac{2.90}{100}=1,8\left(mol\right)\)
\(n_{CO_2}=n_{O_2}=n_C=1,8\left(mol\right)\)
\(m_{CO_2}=1,8.44=79,2\left(g\right)\)
\(m_{O_2}=1,8.32=57,6\left(g\right)\)
