Unformatted text preview: Name: ___________________________________ CH101 Stoichiometry – Study Guide section 4.2 in the textbook Stoichiometry Read about mole‐to‐mole conversions and then write conversions for each of the following based on the balanced equation shown: 2 CH3OH + 3 O2 2 CO2 + 4 H2O Show how to convert from 3.56 moles of CH3OH to the number of moles of O2 required. (ans: 5.34 moles O2) Calculate the number of moles of water formed when 15.0 moles of O2 completely react. (ans: 20.0 moles H2O) You will also need to be able to calculate more complex stoichiometry problems, such as those shown below. mass A moles A moles B mass B The above converts from the mass of one substance in a balanced equation to the mass of another substance. Other possible conversions: mass A moles A moles B mass A moles A moles B particles B Read the example questions in your textbook in this section.
