Chemical Quantities

Chemical Quantities. Or How I Learned to Love the Mole. Conservation. What is the law of conservation of matter? In a chemical reaction, matter is neither created or destroyed. In other words molecules can be converted and decomposed but atoms are forever and are always fully accounted for.

Chapter 6

Chapter 6. Chemical Quantities. How you measure how much?. You can measure mass, or volume, or you can count pieces. We measure mass in grams. We measure volume in liters. We count pieces in MOLES. Moles. Defined as the number of carbon atoms in exactly 12 grams of carbon-12.

The Mole

The Mole. How We Can Accurately Measure Atoms. Remember the Mass of an Atom. An AMU stands for atomic mass unit. The AMU for any element or molecule is found by simply using the average mass value from the p. table The AMU for carbon is 12.01115 The AMU for Boron is 10.811. What is a Mole?.
