Chem 107- Activity 8 Gases 4. In the following combustion reaction, 0.189 mols of CH, are reacted with 1.75 mols of O, What CO, could be produced from this reaction at 125 C and 2.50 atm? volume of 5. A sample of potassium chlorate was heated in a test-tube and decomposed by the following reaction: The oxygen produced was collected via water displacement at 22°C, and a total pressure of 754 torr. The vapor pressure of water at 22°C is 21 torr. The volume of the gas collected was 0550. Calculate: 1.The partial pressure of O, in the gas collected; 2. The mass of KCIO, (MMs 122.55 g/mol) that decomposed. 2KCIO,(s)→2KCl(s) + 3021g)
