W. hen . gases react, the volumes of the reactants and products react in whole. -number . ratios if the temperatures and pressures are constant. . Step-by-Step Mass to Mole. 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. It’s a process that allows us to mathematically convert and calculate the relationships between the amount of reactants and products in a chemical reaction.. Graphical representation . Example: . for every O2 molecule,. Guiding Questions. How are dosages determined? . How are toxins measured and controlled?. . Which is better: eating beans and rice at separate meals . or together?. . Table of Contents. ‘Stoichiometry’. Using ratios of balanced reactions to manipulate the chemical variables in these reactions. Calculators, reference tables, notes.. Get your thinking caps on!. For every single chemical reaction that’s balanced, we can determine the . 1 mole of a substance is 6.02 x 10. 23. . representative particles. .. Avogadro’s number = . 6.02 x 10. 23. Avogadro determined the difference between atoms and particles.. Representative particle. Use . the coefficients to predict the amount of reactant consumed or product formed. The ratio of the coefficients is a ratio of the moles taking part in a reaction.. Reactants (on the left of the arrow) are consumed. Molar Volume. 1 . mol. of gas = 22.4 L .  molar volume. What volume would be occupied by 0.77 moles of helium gas at STP?. Density of Gases. Density = molar mass/molar volume. What is the density of (in grams per liter) of carbon dioxide gas at STP?. wwwmojesnetUnderstanding of Macroscopic Microscopic and Symbolic Representations Among Form Four Students in Solving Stoichiometric Problems Kamariah Binti Sujak 1 Esther Gnanamalar Sarojini Daniel 2 2. .. 2.)
