What is Stoichiometry. Stoichiometry is the study of the relationships or ratios between two or more substances undergoing a physical or chemical change. We will be taking steps to solve the different equations. Should have had all this in CS 252 – Quick review. Many problems have an exponential number of possibilities and we can try each option against some objective to get an answer. Note that this "testing" is fast (always polynomial!). A solution is a homogeneous mixture of two or more substances. Homogeneous – uniform characteristics throughout. Heterogeneous – different compositions; various throughout. Solutions have at least two components. wwwmojesnetUnderstanding of Macroscopic Microscopic and Symbolic Representations Among Form Four Students in Solving Stoichiometric Problems Kamariah Binti Sujak 1 Esther Gnanamalar Sarojini Daniel 2 Concept 1 2¥ One mole of NaCl contains 6.022 x 10 NaCl formula units.¥ Use the mole quantity¥x23 ¥ The mass of an atom in amu¥; .g/amu = 1.674 x10-24 gMass of 1 mole of H atoms: 1.674 x10-24H Jennie L.
