Question
How many moles of lead (II) chloride will be formed from a reaction between 6.5 g of PbO and 3.2 g of HCl?
-
0.044
-
0.333
-
0.011
-
0.029
Solution
D.
0.029
The reagent which is present in smaller quantity is called the limiting reagent and the moles of product depends on it and number of moles
=
Here, 1 mole of PbO reacts with 2 moles of HCl, thus PbO is the limiting reagent
0.029 mol
