42 Chapter 2 Environmental Chemistry Section 2.2 Stoichiometry 43 We already know that there are 44 grams per mole of CO" so we do not need to recalculate that. Two moles of butane (2 mol x 58 g/mol 116 g) yields 8 moles of carbon dioxide (8 mol x 44 g/mol 352 g CO2) , So we can set up the following proportion:

Notes: Stoichiometry Stoichiometry is the study of amounts in chemical reactions. When doing stoichiometry problems, you must always begin with a balanced chemical reaction. You will then use the whole number coefficients as molar quantities for each compound, which will help to determine how much reactants are needed to

Topic 9: Stoichiometry (Chapter 9 in Modern Chemistry p. 298) Introduction to Stoichiometry In this topic we will focus on the quantitative aspects of chemical reactions. That’s right; you’ll need your calculators. Composition Stoichiometry (Topic 7) deals with the mass relationships of elements in compounds.

1 Unit 10A Stoichiometry Notes Stoichiometry is a big word for a process that chemist’s use to calculate amounts in reactions. It makes use of the coefficient ratio set up by balanced reaction equations to make connections between the reactants and products in reactions. Stoichiometry

Instead of sulfuric acid, this lab involves two different acids: citric acid and ascorbic acid (both are acids, thus each reacts with NaOH). You can determine the TOTAL amount of acid (total moles of H moles of H from citric acid moles of H from ascorbic acid) present in a juice sample by titration with NaOH, a strong base. Equation 1
