\(n_{AgNO3}=0,2\left(mol\right)\)
\(n_{CaCl2}=0,15\left(mol\right)\)
PT: 2AgNO3 + CaCl2\(\rightarrow\) 2AgCl\(\downarrow\)+ Ca(NO3)2
0,2 0,1 (mol)
\(\Rightarrow\)\(n_{CaCl2pư}=0,1\left(mol\right)\)
\(\Rightarrow n_{CaCl2}\)dư=0,05(mol)
\(\Rightarrow C_{MCaCl2}\)dư =\(\dfrac{0,05}{0,2+0,1}\)=\(\)0,17M
\(\Rightarrow n_{Ca\left(NO3\right)2}=0,1\left(mol\right)\)
\(\Rightarrow C_{MCa\left(NO3\right)2}=\dfrac{0,1}{0,3}=0,3M\)
