Question

Answer 1

a) \(n_{CO2\left(dktc\right)}=\dfrac{15,12}{22,4}=0,675\left(mol\right)\)

   \(n_{Cl2}=\dfrac{28,4}{71}=0,4\left(mol\right)\)

  \(n_{HNO3}=\dfrac{15,75}{63}=0,25\left(mol\right)\)

b) \(m_{N2O}=0,5.44=22\left(g\right)\)

    \(m_{MgSO4}=0,5.120=60\left(g\right)\)

    \(m_{CaCO3}=0,15.100=15\left(g\right)\)

   \(m_{Fe3O4}=2.232=464\left(g\right)\)

  \(n_{SO2\left(dktc\right)}=\dfrac{28}{22,4}=1,25\left(mol\right)\)

  \(m_{SO2}=1,25.64=80\left(g\right)\)

c) \(n_{Cl2}=\dfrac{31,95}{71}=0,45\left(mol\right)\)

  \(V_{Cl2\left(dktc\right)}=0,45.22,4=10,08\left(l\right)\)
