Solution

The correct option is A 33.33%
The balanced equation is:
AgNO3+NaClAgCl+NaNO3

Moles of Silver Chloride = 169.8169.8=1 mol
Moles of NaCl = 29.258.4=0.5 mol

According to the balanced chemical equation, 1 mol of Silver Nitrate requires 1 mol of NaCl.
But the number of mol of NaCl available is 0.5 mol.
Hence, NaCl is the limiting reagent.

Therefore, the moles of Silver Chloride formed = 0.5 mol
Mass of Silver Chloride formed = 0.5×143.3 = 71.6 g

Theoretical yield = 71.6 g
Experimental yield = 27.2 g

Percentage yield
=experimental yieldtheoretical yield×100=27.271.6×100=33.33%
