Chapter 18, Problem 18.53SP

Interpretation Introduction

Interpretation:

The volume of ${\text{O}}_{\text{2}}$ in milliliter that would be obtained by the thermal decomposition of $0.200gofKMn{O}_4$ should be calculated.

Concept introduction:

• $\text{Number}\text{of}\text{mole}\text{=}\frac{\text{Given}\text{mass}\text{of}\text{the}\text{substance}}{\text{Molar}\text{mass}}$
• 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).
• 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.
• Stoichiometric factor is a relationship between reactant and product which is obtained from the balanced chemical equation for a particular reaction.
• $PV=nRT$ This equation is known as ideal gas equation.
