Problem

a. Calculate the density of oxygen, O2, under each of the following conditions:

STP:
1.00 atm and 30.0°C:

Express your answers numerically in grams per liter. 


b. To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 1.2-L bulb, then filled it with the gas at 1.60atm and 21.0°C and weighed it again. The difference in mass was 2.3g . Identify the gas.

Express your answer as a chemical formula.
