Avogadro’s molar gas volume calculation questions and answers. Use n = v/24 with n = mass/Mr. Full lesson with exam questions includes the definition of molar gas volume. A level and GCSE chemistry suitable. All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides is as follows:
Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see thumbnail image)
Slide 3 – explanation of molar gas volume (1 mole of any gas occupies a volume of 24 dm3 (or 24000 cm3) at room temperature and pressure), and explanation of what room temperature and pressure are
Slide 4 – students are introduced to the formula n = v/24 or n = v/24000
Slide 5 – Worked example 1: What volume does 0.25 moles of a gas occupy at rtp? Answer with working out animates onto the screen
Slide 6 – Worked example 2 (answer and working out animate as you click)
Slide 7 – Mini plenary. Three questions of increasing difficulty, to check what students have learnt so far. Answers animate as you click
Slide 8 – Worked example 3 (answer and working out animate as you click)
Slide 9 - Worked example 4(answer and working out animate as you click)
Slide 10 – Mini plenary. Two questions of increasing difficulty, to check what students have learnt so far. Answers animate as you click
