Methane is burned in a Laboratory Bunsen burner to give CO2 and water vapor. Methane gas is supplied to the burner at the rate of 5.0 L/ min ( at temperature of 28° C and a pressure of 773 mm Hg). At what rate must oxygen be supplied to the burner ( at a pressure of 742 mm Hg and a temperature of 26 °C)?
