Chapter 6.8, Problem 2QQ

Interpretation Introduction

Interpretation:

Pathway for finding “moles of B” from “grams of A” using the conversion factors has to be chosen from the given options.

Concept Introduction:

Using the Avogadro’s number, the relationship between the particles number and the number of moles in a substance can be given.  One mole of a substance contains $6.02x{10}^{23}$ particles.

Molar mass of a substance gives a relationship between the number of grams and number of moles of that particular substance.

The Chemical formula subscript also provides relationship between the number of moles of substance to the number of moles of its individual components present in the substance.

The moles of compound are related to moles of another compound by the coefficients present in the balanced chemical equation.

All the above relationship can be put into a single diagram as shown below,
