2.2 Mole Concept

How are measurements made in chemistry?

Inquiry Question

Overview

  • Conduct a practical investigation to demonstrate and calculate the molar mass (mass of one mole) of:
    • An element
    • A compound
  • Conduct an investigation to determine that chemicals react in simple whole number ratios by moles
  • Explore the concept of the mole and relate this to Avogadro’s constant to describe, calculate and manipulate masses, chemical amounts and numbers of particles in:
    • Moles of elements and compounds n=\frac{m}{MM} (n = chemical amount in moles, m = mass in grams, MM = molar mass in gmol-1)
    • Percentage composition calculations and empirical formulae
    • Limiting reagent reactions
