A flask with a sample of gas at room temperature and pressureweighs 97.4842 g. The same flask with air (density = 1.17 g/L)weighs 96.8848 g. The same flask filled with water (d = 0.998 g/mL)weighs 345.86 g. The pressure in the room is 0.989 atm and thetemperature is 22.2 °C.

1. Calculate the volume of the flask.

2. Calculate the mass of the air that the flask can hold.

3. Calculate the mass of the empty (no air) flask.

4. Calculate the mass of the gas in the flask.

5. Use the Ideal gas law to calculate the moles of gas in theflask.

6. Calculate the molar mass of the gas in the flask.
