Year 11 Chemistry

Module 2 | Introduction to quantitative chemistry

Content 3: Concentration and molarity

Lesson 1 | How are chemicals in solutions measured?

• conduct practical investigations to determine the concentrations of solutions and investigate the different ways in which concentrations are measured (ACSCH046, ACSCH063)

Lesson 2 | Preparing and diluting solutions

• conduct an investigation to make a standard solution and perform a dilution

• Manipulate variables and solve problems to calculate concentration, mass or volume using:
c$\frac{n}{V}$ (molarity formula) (ACSCH063)
– dilutions (number of moles before dilution = number of moles of sample after dilution)

Lesson 3 | Calculating concentrations

• Manipulate variables and solve problems to calculate concentration, mass or volume using:

– $c = \frac{n}{V}$ (molarity formula) (ACSCH063)
– dilutions (number of moles before dilution = number of moles of sample after dilution)
