\(2Fe+3Cl_2\rightarrow\left(t^o\right)2FeCl_3\\ n_{FeCl_3}=\dfrac{6,5}{162,5}=0,04\left(mol\right)\\ n_{Fe}=n_{FeCl_3}=0,04\left(mol\right)\Rightarrow m=m_{Fe}=0,04.56=2,24\left(g\right)\\ n_{Cl_2}=\dfrac{3}{2}.0,04=0,06\left(mol\right)\Rightarrow V=V_{Cl_2\left(đkc\right)}=0,06.24,79=1,4874\left(l\right)\)
