(a)
Interpretation: The number of moles of chloride ions and number of moles of iron ions has to be calculated
Concept Introduction: Molarity: Molarity is defined as the number of moles of solute in one liter of solution. Molarity is the preferred concentration unit for stoichiometry calculations. The formula is,
(a)
Answer to Problem 54A
The number of moles of iron ions is
The number of moles of chloride ions is
Explanation of Solution
The molarity of iron (III) chloride is
The volume of iron (III) chloride is
The molarity of
The solution contains 3.00 moles of
The number of moles of iron ions is
The number of moles of chloride ions is
(b)
Interpretation: The mass of solid product formed (in grams) has to be determined.

(b)
Answer to Problem 54A
The mass of solid product formed (in grams) is
Explanation of Solution
Iron (III) chloride contains
The limiting reagent is identified by calculating the moles of
Moles=
Moles=
The moles of lead (II) ions is
The solution contains
The moles of chloride ions is
The chloride ions are present in excess, so only 2.00 moles of solid
The molar mass of lead (II) chloride is
Mass of solid lead (II) chloride is calculated as,
Mass of solid lead (II) chloride=
Mass of solid lead (II) chloride=
The mass of solid product formed (in grams) is
