Introduction to Quantitative Chemistry 2

MDQ2   How are measurements made in Chemistry?

2.1a    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=𝑚/𝑀𝑀 (n = chemical amount in moles, m = mass in grams, MM = molar mass in gmol-1)

2.1b    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: 

– percentage composition calculations and empirical formulae

2.1c    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: 

– limiting reagent reactions

2.2  conduct a practical investigation to demonstrate and calculate the molar mass (mass of one mole) of:

– an element

– a compound 

2.3   conduct an investigation to determine that chemicals react in simple whole number ratios by moles
