Chapter 9.5, Problem 9.28QAP

Interpretation Introduction

(a)

Interpretation:

To determine percent yield of iron if 15.0 g of iron produces from 65.0 g of iron (III) oxide.

Concept Introduction:

A stoichiometric coefficient of a well-balanced chemical equation tells about the relative relation between moles of reactants used and moles of products formed.

Lets say we have a chemical reaction as:

  $\text{aA}\text{+bB}\to \text{cC}\text{+}\text{dD}$

If above reaction is well-balanced then,

a moles of A reacts with b moles of B to produce c moles of C and d moles of D.

Formula to calculate percentage yield:

  $\text{percent}\text{yield}\text{=}\frac{\text{experimental}\text{yield}}{\text{theoritical}\text{yield}}\text{×100}$

Interpretation Introduction

(b)

Interpretation:

To determine percent yield of carbon dioxide if 85.0 g of carbon dioxide produces from 75.0 g of carbon monoxide.
