200ml = 0,2l
\(n_{NaOH}=2.0,2=0,4\left(mol\right)\)
Pt : \(NaOH+HCl\rightarrow NaCl+H_2O|\)
1 1 1 1
0,4 0,4 0,4
a) \(n_{HCl}=\dfrac{0,4.1}{1}=0,4\left(mol\right)\)
400ml = 0,4l
\(C_{M_{ddHCl}}=\dfrac{0,4}{0,3}=1,3\left(M\right)\)
b) \(V_{ddspu}=0,2+0,3=0,5\left(l\right)\)
c) \(n_{NaCl}=\dfrac{0,4.1}{1}=0,4\left(mol\right)\)
\(C_{M_{NaCl}}=\dfrac{0,4}{0,5}=0,8\left(M\right)\)
