Chemistry Moles Packet. INTRODUCTION TO MOLES. We are about to start on a unit of chemical calculations called “stoichiometry”. Stoichiometry is how we calculate the relationships between the amounts of reactants and the amounts of products.
Description. This unit uses a discovery-based method to introduce the mole concept without relying on students’ strong background. The lessons contain activities with candy that lead students to develop the rules for mole-item, item-mole, mole-mass, and mass-mole “conversions.”
answer. The only new concept we will introduce in this unit is the idea of a mole. A mole is a quantity of matter that we use for conversion purposes. We can convert from grams to moles and atoms or molecules to moles.
11 sty 2022 · The Mole. The Avogadro constant (NA or L) is the number of particles equivalent to the relative atomic mass or molecular mass of a substance in grams. The Avogadro constant applies to atoms, molecules and ions. The value of the Avogadro constant is 6.02 x 1023 g mol-1.
