\(n_{KCl}=0,02.2=0,04\left(mol\right)\)
\(n_{AgNO_3}=0,05.0,1=0,005\left(mol\right)\)
PTHH: KCl + AgNO3 --> KNO3 + AgCl\(\downarrow\)
Xét tỉ lệ \(\dfrac{0,04}{1}>\dfrac{0,005}{1}\) => KCl dư, AgNO3 hết
PTHH: KCl + AgNO3 --> KNO3 + AgCl\(\downarrow\)
__________0,005---------------->0,005
=> mAgCl = 0,005.143,5 = 0,7175(g)
=> A
