Chapter 9.5, Problem 9.27QAP

Interpretation Introduction

(a)

Interpretation:

To determine percent yield of carbon disulphide if 36.0 g of carbon disulphide produces from 40.0 g of carbon.

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 disulphide if 12.0 g of carbon disulphide produces from 32.0 g of SO₂.
