What is the density (in g/L) of SF4 vapor at 735 torr and 496 K? Calculate the number of grams of carbon dioxide that are contained in a 7.43 L container at 68.5 °C and 2.97 atmospheres pressure. A substance has a heat of vaporization of 19.7 kJ/mol. If it has a vapor pressure of 428 mmHg at 14oC, what will the vapor pressure be at 46oC? Round your answer to a whole number (no decimal places) and be sure...

A container of carbon dioxide gas has a volume of 50.0 L. When originally purchased, the tank guage showed a pressure of 10.0 atm at 20.0 degrees celcius. After one month's use, the tank pressure was 6.10 atm at 15.0 degrees celcius. How many grams of CO2 were used during the month? Molar Mass of CO2 is 44.01 g/mol.
