Chapter 22.6, Problem 4CS

Interpretation Introduction

Interpretation:

Concentration cerium salt in the in the given compound has to be calculated..

 Concept introduction:

• Concentration of solutions can be expressed in various terms; molarity is one such concentration expressing term.
• Molarity (M) of a solution is the number of gram moles of a solute present in one liter of the solution.

     $\text{Molarity}\text{=}\frac{\text{Mass}\text{per}\text{litre}}{\text{Molecular }\text{mass}}$

• A solution containing one gram mole or $\text{0}\text{.1}$ gram of solute per litre of solution is called molar solution.
• Amount of substance (mol) can be determined by using the equation,                      

    $\text{Number}\text{of}\text{mole}\text{=}\frac{\text{Given}\text{mass}\text{of}\text{the}\text{substance}}{\text{Molar}\text{mass}}$

• The molar mass of an element or compound is the mass in grams of 1 mole of that substance, and it is expressed in the unit of grams per mol (g/mol).
• $\text{Concentration}\text{of}\text{substance}\text{=}\frac{\text{Amount}\text{of substance}}{\text{volume}\text{of}\text{the}\text{substance}}$
• For chemical reaction balanced chemical reaction equation written in accordance with the Law of conservation of mass.
• Law of conservation of mass states that for a reaction total mass of the reactant and product must be equal.
