E. Teaching Materials

If we are reacting the carbon atom (C) with one molecule of oxygen (O2), it will form one molecule of CO2. But the fact that we are not one atom of Carbon reaksikan with one molecule of oxygen, but a large number of carbon atoms and a large number of oxygen molecules. Therefore, the number of atoms or number of molecules reacting yamg so great, then to state, the chemists use the "mole" as the unit number of particles (molecules, atoms, or ions).

One mole is defined as the amount of substance that contains as many atomic particles of matter contained in 12.000 grams of carbon atoms – 12. So in one mole of a substance contained 6.022 x 10 23 particles. Value of 6.022 x 10 23 particles / mol Avogadro constant is referred to as, the symbol of L or N. In everyday life, we can mole analogy as "dozen". If a dozen states the number of 12 pieces, then declare the amount of 6.022 mol x 10 23 particles of matter. Word particle in NaCl, H2O, N2 can be expressed by the ions and molecules, while the elements such as Zn, C, Al can be expressed by the atom.

Consider the following table. Table 06.6 The number of particles within some substance.

The chemical formula of a compound shows a comparison of the number of atoms present in the compound.

Table 06.7 Comparison of the atoms in H₂SO₄

1 mole of substance contains 6.022 x 10 23 particles

example:

One water molecule (H2O) are 6.022 x 10 23 molecules of H2O.

How many atoms in one mole of water?

Answer:

One water molecule (H2O) is composed of two H atoms and one O atom

So a water molecule is composed of three atoms.

1 mole of H2O contains 6.022 x 10 23 molecules or

3 x 6.022 x 10 23 atoms = 1.806 x 10 23 atoms

F. Methods and models of learning

·         Methods                 : Lecture varied (discussions, questions and answers)

·         Model Learning     : Cooperative Learning (Cooperative Learning)

·         Approach Learning: The Concept and Process Approach

G. Learning steps

Material  - The solution

-  Studying the nature - the nature of electrolyte and non electrolyte solution

Activity	Phase	Activities of Teacher	Allocation of time	Done / not
Initial / The introduction	Orientation	Opening: The teacher creates a classroom atmosphere that is religious by appointing one of the students led the prayer, checking attendance.	5 minutes
	Apperception	The teacher gives apresepsi reminiscent of the fundamental laws of chemistry and its relative atomic mass (Ar) and the relative molecular mass (Mr) and students with a sense of responsibility to give examples of objects
	Motivation	Teachers to motivate students in communicative and creative with a few questions relating to the mol concept.
	Provision of Reference	Teachers submit material outlines the scope of mol concept that will be done.
Core Activities	Exploration	a Teachers divide students into small groups. Each group consisted of 4-5 students. Students talk about definition about mol b. Each - each group to discuss and conclude discuss and conclude the sense mole as a unit amount of substance as well as the relationship between the number of moles of a substance by the number of particles contained in the substance responsibly and independently in accordance with the instructions provided c. Students pay attention to teachers' presentations on the relationship between the mass in units of moles, and apply them in the calculation of chemical c. Each group was asked his opinion about the reasons independently and responsibly.	70 minutes
	Elaboration	1.   Each group present the results discussion.  independently  and responsible 2.   Students work hard in doing discussion about mol concept
	Confirmation	1.Teachers provide feedback and conclusions based on a group work communicativediscussions. 2.Teachers give reasons for the strengthening of mol concepts in a responsible manner. 3. Teachers creatively provide important records about the subject matter that must be controlled by students.
Closing	Achievement Reflection	1.    Teacher give assessment to each group which is presentating result of its discussion 2.    Teachers also give a personal assessment to any student who asks and respond to discussions of other groups 1. The teacher gives feedback on the material that has been taught in a democratic manner. 2. Teachers plan a follow-up activities on their own in the form of remedial teaching, enrichment program, an intellectually counseling and / or gas tu assign either individually or in groups according to the study of students 3. Teachers foster curiosity of the student thatto likes reading by making the individual lab reports, and collected at the next meeting 4. Students (teacher-led) summarizes the material concept of the mole. 5. The teacher explains the core concepts of the material concept of the mole that has been concluded as a reinforcement.	15 minutes
