Ta có: \(\left\{{}\begin{matrix}n_{HCl}=0,5.0,2=0,1\left(mol\right)\\n_{H_2SO_4}=0,5.0,3=0,15\left(mol\right)\end{matrix}\right.\)
\(n_{FeO}=\dfrac{14,4}{72}=0,2\left(mol\right)\)
PT: \(FeO+2HCl\rightarrow FeCl_2+H_2O\)
____0,05___0,1______0,05 (mol)
\(FeO+H_2SO_4\rightarrow FeSO_4+H_2O\)
0,15____0,15______0,15 (mol)
⇒ m muối = mFeCl2 + mFeSO4 = 0,05.127 + 0,15.152 = 29,15 (g)
→ Đáp án: B
