A rigid 7.80 L sealed vessel containing 2.700 mol of O2(g), 0.60 0 mol of C2H4(g), and 2.400 mol of Ne(g) has an internal temperature of 85.0∘C
a. Calculate the total pressure in the cylinder.
b. Find the mole fraction of O2 in the vessel.
c. A lab technician ignites the mixture in the vessel and the following reaction occurs:
C2H4(g)+3O2(g)→2CO2(g)+2H2O(g)
Find the mole fraction of each gas in the vessel after the reaction.
