Question

How many moles of lead (II) chloride will be formed from a reaction between 6.5 g of PbO and 3.2 g HCl? 

(a) 0.011 

(b) 0.029 

(c) 0.044 

(d) 0.333

Answer 1

The correct option is : (b) 0.029 

Explanation :

Formation of moles of lead (lI) chloride depends upon the no. of moles of PbO which acts as a limiting factor here. So, no. of moles of pbCl₂ formed will be equal to the no. of moles of PbO i.e. 0.029.
