Unformatted text preview: Chem 124 Fall 2008 Show your calculation of the gas constant R: Group Data & Statistics To fill in the table below, get experimental “R” values from other students in the class, either at your table or tables near you. Include your value in this table also. Calculate an average “R” and the standard deviation. You can do these calculations in Excel. Computer # Value of “R” in L•atm/mol•K Average “R” value Standard Deviation QUESTIONS 1. Oxygen can be generated by the thermal decomposition of potassium chlorate, as described by the following equation: heat KClO 3 (s) KCl (s) + O 2 (g) NOT BALANCED Calculate the volume of oxygen gas, measured at 27.5 ˚ C and 743 torr, produced by the decomposition of 2.75 g of potassium chlorate.
