\(n_{Cu(NO_3)_2}=1,5.0,2=0,3(mol)\\ PTHH:Cu(NO_3)_2+2NaOH\to Cu(OH)_2\downarrow+2NaNO_3\\ a,n_{Cu(OH)_2}=0,3(mol)\\ \Rightarrow m_{Cu(OH)_2}=0,3.98=29,4(g)\\ b,n_{NaOH}=0,6(mol)\\ \Rightarrow V_{dd_{NaOH}}=\dfrac{0,6}{2}=0,3(l)\\c,n_{NaNO_3}=0,6(mol)\\\Rightarrow C_{M_{NaNO_3}}=\dfrac{0,6}{0,3}=2M\)
\(d,Cu(OH)_2+2HCl\to CuCl_2+2H_2O\\ \Rightarrow n_{HCl}=2n_{Cu(OH)_2}=0,6(mol)\\ \Rightarrow m_{dd_{HCl}}=\dfrac{0,6.36,5}{10\%}=219(g)\\ \Rightarrow V_{dd_{HCl}}=\dfrac{219}{1,1}=199,09(ml)\)
