At the end of the lesson, students should be able to 1 define and distinguish the terms relative atomic mass, relativemolecular mass and relativeformula masses, based on the 12C scale 2 calculate the percentage mass of an element in a compound when given appropriate information
Lesson 2:
At the end of the lesson, students should be able to 1 define the term mole in terms of the Avogadro constant. 2 define molar mass. 3 determine the no of moles from the given mass and the molar mass of any substances.
