a)
\(n_{Al}=\dfrac{4,05}{27}=0,15\left(mol\right)\)
PTHH: \(2Al+6HCl\rightarrow2AlCl_3+3H_2\)
0,15-->0,45----->0,15--->0,225
V = 0,225.22,4 = 5,04 (l)
b) \(m_{HCl}=0,45.36,5=16,425\left(g\right)\Rightarrow m_{dd.HCl}=\dfrac{16,425.100}{10}=164,25\left(g\right)\)
\(n_{Al}=\dfrac{4,05}{27}=0,15\left(mol\right)\)
\(2Al+6HCl\rightarrow2AlCl_3+3H_2\)
0,15 0,45 0,15 0,225
\(V_{H_2}=0,225.22,4=5,04\left(l\right)\)
\(m_{ddHCl}=\dfrac{0,45.36,5.100}{10}=164,25\left(g\right)\)
