The mole concept
This section includes a wide range of practical activities providing opportunities to apply the concept of the mole. Empirical and molecular formulae, reacting masses, % yield, volumes of gases and titration calculations are all covered.
While we are still at an early stage with this website it's probably more useful to look at the page with our complete list of experiments in alphabetical order. See the list on About this website.
We are starting with GCSE-level experiments.

Experiments
-
A thermometric titration
A titration between sodium hydroxide and hydrochloric acid using the accompanying temperature change as a means of determining the end-point.
-
Determination of Relative Atomic Mass
The relative atomic mass of magnesium is determined by reacting a known mass of magnesium with dilute acid and measuring the volume of hydrogen produced.
-
Finding the formula of hydrated copper(II) sulfate
The formula of hydrated copper(II) sulfate is found by heating a sample to remove the water of crystallisation.
-
Determining the relative molecular mass of butane
A simple, quick and direct method for finding relative molecular masses (RMM) of gases, such as butane, that are available in small pressurised cylinders.
-
Determining relative molecular masses by weighing gases
A fairly quick and reasonably direct method for finding the relative molecular masses (RMM) of common gases, by weighing a 50 cm^3^ gas sample.
