Câu 1:
a, \(V_{CO_2}=0,6.22,4=13,44l\)
\(b,V_{NH_3}=0,2.22,4=4,48l\)
\(c,V_{O_2}=0,15.22,4=3,36l\)
\(d,V_{Cl_2}=0,3.22,4=6,72l\)
Câu 2:
\(a,n_{SO_2}=\dfrac{4,48}{22,4}=0,2mol\)
\(b,n_{CuO}=\dfrac{4}{80}=0,05mol\)
\(c,n_{MgO}=\dfrac{25}{40}=0,625mol\)
\(d,n_{CuCl_2}=\dfrac{2,7}{135}=0,02mol\)
\(e,n_{NO_2}=\dfrac{5,04}{22,4}=0,225mol\)
\(f,n_{Cu}=\dfrac{2,4.10^{23}}{6.10^{23}}=0,4mol\)
