1.
a. Ta có: \(n_{SO_2}=\dfrac{0,64}{64}=0,01\left(mol\right)\)
\(\Rightarrow V_{SO_2}=0,01.22,4=0,224\left(lít\right)\)
b. Ta có: \(n_{Cl_2}=\dfrac{1,2.10^{23}}{6.10^{23}}=0,2\left(mol\right)\)
\(\Rightarrow V_{Cl_2}=0,2.22,4=4,48\left(lít\right)\)
3.
Ta có: \(n_{O_2}=\dfrac{3,36}{22,4}=0,15\left(mol\right)\)
\(\Rightarrow Số.phân.tử.của.3,36.lít.O_2=0,15.6.10^{23}=9.10^{22}\left(phân.tử\right)\)
