To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an emply 5.0 - L bulb, then filled it with the gas at 1.20atm and 30.0C and woighed it again. The difference in mass was 6.7g. Identify the gas. Express your answer as a chemical formula. MISSED THIS? Watch IWE 10.7, Read Section 10.6. You can cilck on the Review fink to access the section in your otext. What must be the pressure of the gas? A sample of N2O gas has a density of 2.70g/L at Express your answer in millimeters of mercury. 298K.
