Mole Calculations Moles and Number 1 mole of any substance contains the same number of atoms/molecules/ions as there are atoms in a 12g sample of carbon -12 12g of carbon-12 contains a constant number of atoms. This number is known as the Avogadro constant (L) and is equal to 6.02 x 1023. 1 mole of carbon-12 contains 6.02 x 1023 atoms. Therefore‚ 1 mole of any substance contains 6.02 x 1023 atoms/molecules/ions. For example‚ 1 mole of aluminium contains 6.02 x 1023 Al atoms 1

Cup o’ Noodles: Through the Eyes of a Chemist Background: Before completing this experiment‚ one must know about chemical formulas‚ ionic bonding‚ solutions and moles to understand the results of this experiment. A chemical formula is the symbol for compounds and elements. It tells chemists how many atoms are in a chemical compound‚ formula unit or molecular compound. In a chemical formula a subscript indicates how many atoms there are of an element before it. The coefficient in a chemical formula

CONCENTRATION AND DILUTION Physiology 1‚ Las Positas College Name: In science‚ concentration is a measure of the number of particles (solutes) in a given volume. If one room has 100 people in it‚ and a room of equal size has 50 people‚ one can say that the concentration of people in one room is twice that of the other. Quite simple‚ isn’t it? On a molecular level‚ consider whether you put one lump or two of sugar‚ or no sugar at all‚ in your coffee. If you use two lumps‚ you prefer twice

Abstract Bipolar Disorder is a mental illness in which a person’s mood alternates between extreme mania and depression. Bipolar disorder is also called manic-depressive illness. In a related disorder called cyclothymic disorder (sometimes called Bipolar III)‚ a person’s mood alternates between mild depression and mild mania. Some people with cyclothymic disorder later develop full-blown bipolar disorder. Rates of bipolar disorder are similar throughout the world. At least fifteen percent of people
