Molecular compounds
Molecular compounds are made of molecules. each molecule contains anywhere from two atoms (diatomic molecules) to thousands (biological molecules). each molecule has the same element composition and properties as the compound.

Measurement
Measurement is the collection of quantitative data. The proper handling and interpretation of measurements are essential in chemistry - and in any scientific endeavour. To use measurements correctly, you must recognize that measurements are not numbers. They always contain a unit and some inherent error. The second lecture focuses on an international system of units (the SI system) and introduces unit conversion. In the third lecture, we'll discuss ways to recognize, estimate and report the errors that are always present in measurements.
