CHE101 Gases Instructor: HbR. Elements that exist as gases at 25 0 C and 1 atmosphere. Physical Characteristics of Gases. Gases assume the volume and shape of their containers. Gases are the most compressible state of matter.

The Mole Concept. Avogadro’s Number. Avogadro’s Number (symbol N ) is the number of atoms in 12.01 grams of carbon. Its numerical value is 6.02 × 10 23. Therefore, a 12.01 g sample of carbon contains 6.02 × 10 23 carbon atoms. The Mole.

Counting Atoms. Chemistry is a quantitative science - we need a "counting unit." The MOLE 1 mole is the amount of substance that contains as many particles (atoms or molecules) as there are in 12.0 g of C-12. AvogadroPaper. The Mole is Developed. Avogadro’s number.

How Big is a Mole?. One mole of marbles would cover the entire Earth (oceans included) for a depth of two miles. One mole of $1 bills stacked one on top of another would reach from the Sun to Pluto and back 7.5 million times. It would take light 9500 years to travel from the bottom

Molarity. Concentration Based on Mass. Concentration - amount of solute dissolved in a given amount of solution Concentration of a solution has an effect on Physical properties Melting and boiling points Chemical properties Solution reactivity. Moles and Equivalents.

Chapter 10 Chemical Quantities. Get ready for some serious finger exercise!. 10.1 The Mole: Measurement of Matter. OBJECTIVES: Describe methods of measuring the amount of something Define Avogadro’s number as it relates to a mole of a substance

Ch. 7 Part 1 – The Mole. Molar Conversions (p.80-85, 221-226). VERY. A large amount!!!!. A. What is the Mole?. A counting number (like a dozen) Avogadro’s number (N A ) 1 mol = 6.02  10 23 items. A. What is the Mole?. HOW LARGE IS IT???.

9.1 NOTES Stoichiometry. I. What is Stoichiometry? Definition: the study of quantitative relationships between the amounts of reactants used and products formed by a chemical reaction; based on the law of conservation of mass and energy.

Stoichiometry. The quantitative study of reactants and products in a chemical reaction. • Whether the units given for reactants or products are moles , grams , liters (for gases), or some other units, we use moles to calculate the amount of product formed in a reaction.

Do Now. If I have 1 dozen bagels, how many bagels do I have? _____ If I have 4 dozen bagels, how many bagels do I have? _____ If I have 0.5 dozen bagels, how many bagels do I have? _____ What weighs more: A pound of feathers or A pound of lead?. Day 1 - Notes. Unit: Chemical Quantities.

Stoichiometry. “In solving a problem of this sort, the grand thing is to be able to reason backward. This is a very useful accomplishment, and a very easy one, but people do not practice it much.”. Stoichiometry - The study of quantities of materials consumed and produced in chemical reactions.
