Explanation:
PbO+2HCl→PbCl
2
+H
2
O
Atomic mass of PbO = 207 + 16 = 223
Atomic mass of HCl = 36.5
Moles of PbO =
223
6.5
= 0.029 moles
Moles of HCl =
36.5
3.2
= 0.088 moles
From the above chemical equation, we see that PbO is the limiting reagent.
∴ 1 mole of PbO gives 1 mole of PbCl
2
0.029 moles of PbO forms 0.029 moles of PbCl

.
Hence, the answer is option B.
