9 Chemicalcalculations Lessonplan Vinay

# Instructional Objectives

- Should be able to define relative atomic mass on carbon 12 scale.
- Should know mole concept and its connection to avagadro number.
- Application of moles to various elements, compounds, gases and solutions.
- Interrelation b/w mole, avagadro number, atomic weight and volume of gases and do the related calculations.
- Concept of emperical and molecular formula and finding them using the mole concept.
- Should be thorough with units in chemical calculations.
- Calculate the relative atomic mass of an element given the relative abundances of its isotopes

# Teaching Process

- All the above concepts are taught with hand on experiments (Calculation with liquids) and numerical calulations

# Suggested reading

- Practice problems from ICSE textbook.

# Activities

- Titration is taught in detail. Students will perform titration with reactions prescribed in the syllabus

# Assignments and Evaluations

- This topic needs extensive problem solving. Hence problem sheets will be given at appropriate times.
