- B \(69.4\)
- C \(91.5\)
- D \(162.5\)
Answer & Solution
Correct Answer
(C) \(91.5\)
Step-by-step Solution
Detailed explanation
\(4 HNO _{3}(\ell)+3 KCl ( s ) \rightarrow Cl _{2}( g )+ NOCl\) \(( g )+2 H _{2} O ( g )+3 KNO _{3}( g )\) \(x \;g m \quad \quad 110\; gm\) \(\frac{ x }{63} \quad \quad Mole =\frac{110}{101}\) \(4 \rightarrow 3\) \(1 \rightarrow \frac{3}{4}\)…
