a sample of an ideal gas in a 200.0 mL bulb until ts pressure was 770 torr at temperature of 30.0°C. If the sample weighed 0.425 g, what is its molecular weight? 8. 167 torr of NO2 and 0.780 atm of O2 are placed in a 1.00 L container at 27.0°c. a. What is the total pressure in torr? b. What are the mole fractions with respect to NO2 and O2? c. If the volume of the container is reduced to 500.0 mL what will the new pressure be? The temperature of the container remains constant and is 27.0°C.
