Ethane burns in air to give H2O and CO2.

2 C2H6(g) + 7 O2(g) â 4 CO2(g) + 6 H2O(g)

A 2.78 L flask contains C2H6 at a pressure of 252 mm Hg and a temperature of 25Â°C. Suppose O2 gas is added to the flask until C2H6 and O2 are in the correct stoichiometric ratio for the combustion reaction. At this point, what is the partial pressure of O2?

P(O2) =_____mm Hg
