Fоr the reаctiоn belоw, O2 is the limiting reаgent. If {mo} mol of TO2 аre produced, how many moles of O2 were completely used in the reaction? T2H4 + 3 O2 --> 2 TO2 + 2 H2O You may not need any or all of the information below: Molar Mass of T2H4 = 28.05 g/mol Molar Mass of O2 = 32.00 g/mol Molar Mass of TO2 = 44.01 g/mol Molar Mass of H2O = 18.02 g/mol For full credit, your answer must: Contain 2 significant figures Include the proper abbreviation for units
