Unformatted text preview: Solution Where are we going? • To determine the partial pressure of O 2 in the gas collected • Calculate the mass of KCl0 3 in the original sample What do we know? Gas Collected Water Vapor P 754 torr 21 torr V 0.650 L T 22°C + 273 = 295 K 22°C + 273 = 295 K How do we get there? What is the partial pressure of 02? PTOTAL = Po, + PH,o = Po, + 21 torr = 754 torr • Po, = 754 torr 21 torr = 733 torr What is the number of moles of 02? Now we use the ideal gas law to find the number of moles of 02: Po,V n0, RT...
