Molar volume of oxygen lab. Since the reaction occurs at STP, the volume ratio is directly proportional to the molar ratio, so 1 L C 2 H 2 produces 2 L C O2 . 32 g/mol 3 C. 00 mol. 2 days ago · Next, calculate the moles of oxygen gas using the molar volume at STP: Moles of O2 = 22. Abstract This experiment was done to determine the percent chloric acid, or KClO 3 , in a heterogeneous mixture and to determine the molar volume of oxygen gas at 273 K and 760 torr. From this information, you are able to calculate the molar volume of oxygen at STP (i. The numerical value of R is found from the values measured in lab for the partial pressure of O2(PO2), the volume, the number of moles of O2 (n), and the temperature. You measured the mass of oxygen produced from your sample, as well as the volume of oxygen (by displacement of water). 6667 mol. 4 liters at STP.
