CHEM 110 Recitation 9 1 Recitation 9 Learning Objectives: What is Pressure • Be able to define pressure and some ways to measure pressure. • Be able to define barometric pressure. • Know how a manometer is used to measure pressure • Know how to use an open ended versus a closed ended manometer to determine gas pressure Ideal Gas Law • Know the relationships between pressure, volume, temperature, and moles of an ideal gas. (PV=nRT). • Be able to use Boyle’s Law, Charles’s Law, Avogadro’s Law appropriately given experimental information. • Be able to interpret plots that express Boyle’s Law, Charles’s Law, Avogadro’s Law, or the ideal gas law. • Be able to use the ideal gas law to calculate P, V, T or n of a gas sample given the necessary experimental information. • Know what is meant by STP. • Know the value of and what is meant by the gas constant R. • Be able to determine the density of a gas using the ideal gas law and molar mass.
