1. \(n_{O_2}=\frac{V}{22,4}=\frac{6,72}{22,4}=0,3\left(mol\right)\)
2.
\(n_{CO_2}=\frac{m}{M}=\frac{4,4}{44}=0,1\left(mol\right)\)
\(n_{O_2}=\frac{m}{M}=\frac{3,2}{32}=0,1\left(mol\right)\)
\(V_{HC}=n.22,4=\left(0,1+0,1\right).22,4=4,48\left(l\right)\)
Câu 1:
\(n_{O_2}=\frac{V}{22,4}=\frac{6,72}{22,4}=0,3\left(mol\right)\)
Câu 2:
\(n_{CO_2}=\frac{m_{CO_2}}{M_{CO_2}}=\frac{4,4}{44}=0,1\left(mol\right)\)
=>\(V_{CO_2\left(đktc\right)}=n_{CO_2}.22,4=0,1.22,4=2,24\left(l\right)\)
\(n_{O_2}=\frac{m_{O_2}}{M_{O_2}}=\frac{3,2}{32}=0,1\left(mol\right)\)
=> \(V_{O_2\left(đktc\right)}=n_{O_2}.22,4=0,1.22,4=2,24\left(l\right)\)
