A sample of oxygen gas has a density of g/L at a pressure of 0.912 atm and a temperature of 47 °C. Assume ideal behavior. A 3.20 gram sample of an unknown gas is found to occupy a volume of 0.939 L at a pressure of 970 . mmHg and a temperature of 46 °C. Assume ideal behavior. The molar mass of the unknown gas is g/mol.
Assume that one liter of ethane (C2H6) measured at 25 ° C and 745 torr is placed in a strong 5.0 L container along with 6.0 g of oxygen gas. The combustion reaction (explosion in this case) is started by a spark. Then the container is cooled to 150 ° C. What is the total pressure in mmHg inside the container? The equation is: 2C2H6g) + 702g) → 4CO2g) + 6H2O @). R / 1.72 atm
