1. Calculate the density of oxygen, O2, under each of the following conditions: STP 1.00 atm and 20.0 ∘C2. To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 3.6-L bulb, then filled it with the gas at 1.30 atm and 20.0 ∘C and weighed it again. The difference in mass was 5.5 g. Identify the gas.3. A sample of gas has an initial volume of 31.6L at a pressure of 1.1 atm. If the sample is compressed to a volume of 10.2 L, what will its pressure be?4. Use the molar volume of a gas at STP to calculate the density (in g/L) of carbon dioxide gas at STP.
