Chapter 7, Problem 7.133AQAP

(a)

Interpretation Introduction

Interpretation: The number of moles of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$which are needed to produce 3.00 moles of ${\text{H}}_{\text{2}}\text{O}$should be determined.

Concept Introduction:The study in which the amount of materials i.e. reactant or products are consumed or produced is known stoichiometry.

Number of moles = $\frac{\text{Given mass}}{\text{Molar mass}}$

The reactant which runs out first and limits the amount of product which can form is known as limiting reagent.

(b)

Interpretation Introduction

Interpretation: The mass of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$in grams which is needed to produce 36.5 g of ${\text{O}}_{\text{2}}$should be determined.

Concept Introduction:The study in which the amount of materials i.e. reactant or products are consumed or produced is known stoichiometry.

Number of moles = $\frac{\text{Given mass}}{\text{Molar mass}}$

The reactant which runs out first and limits the amount of product which can form is known as limiting reagent.

(c)

Interpretation Introduction

Interpretation: The mass of ${\text{H}}_{\text{2}}\text{O}$in grams which is needed to produce when 12.2 g of ${\text{H}}_2{\text{O}}_{\text{2}}$should be determined.
