Practise converting mass, molar mass, moles and particle number with Avogadro's constant, including isotope or molecular composition and kilogram-to-gram unit changes.
This question is in two parts. Part 1 is about ideal gases and specific heat capacity. Part 2 is about simple harmonic motion and waves.
Part 1 Ideal gases and specific heat capacity
Argon behaves as an ideal gas for a large range of temperatures and pressures. One mole of argon is confined in a cylinder by a freely moving piston.
Define what is meant by the term one mole of argon.
One mole of argon is the molecular weight of argon in grams, or 6.02×1023 argon atoms, or the same number of particles as in 12 g of carbon-12.
Allow atoms or molecules for particles.
