How many moles of lead (II) chloride will be formed from a reaction between 6.5 g of PbO and 3.2 g HCl ?
  1. A
    0.011
  2. B
    0.029
  3. C

Correct answer: B

PbO+2HCl$\to$PbCl2+H2O
n mol2n moln mol
$6.5 \over 224$ mol$3.2 \over 36.5$ mol
0.029 mol0.087 mol

Formation of moles of lead(II) chloride depends upon the no. of moles of PbO which acts as a limiting reagent here. So no of moles of PbCl2 formed will be equal to the no of PbO (i.e 0.029)
