a)
\(m_{FeCl_3}=0,025\cdot162,5=4,0625\left(g\right)\)
\(m_{H_2O}=0,5\cdot18=9\left(g\right)\)
\(m_{Cu\left(NO_3\right)_2}=0,35\cdot188=65,8\left(g\right)\)
b)
\(V_{H_2}=0,3\cdot22,4=6,72\left(l\right)\)
\(n_{SO_2}=\dfrac{16}{64}=0,25\left(mol\right)\) \(\Rightarrow V_{SO_2}=0,25\cdot22,4=5,6\left(l\right)\)
\(n_{CO_2}=\dfrac{26,4}{44}=0,6\left(mol\right)\) \(\Rightarrow V_{CO_2}=0,6\cdot22,4=13,44\left(l\right)\)
