What is the purpose of prescribed practical P4? To investigate experimentally the relationship between the mass and volume of liquids and regular solids, and analyse and interpret the data gathered.

The ChemTrix Chemistry Calculator app doesn’t have too many “trix” up its digital sleeve, but the few calculations that it does —calculating the molar mass and mass distributions of user-inputted ...

It is tempting to think that some materials are always heavier than other materials. For example, someone might say that metal is heavier than air. But it depends on how much of each material there is ...
