a flask with a total volume of 0.0800 L is found to contain 0.2911 g of an unknown gas when the pressure and temperature are 1.19 atm and 94 degrees Celcius, respectively. what is the molar mass of the unknown gas?

The experimental rate law for the decomposition of nitrous oxide (N2O) to N2 and O2 is rate = k[N2O]^2. Two mechanisms are proposed: I. N2O N2 + O N2O + O N2 + O2 II. 2N2O <===> N4O2 N4O2 2N2 + O2 Which of the following could be a correct mechanism? (show all...

To identify a diatomic gas (), a researcher carried out the following experiment: She weighed an empty 1.00- bulb, then filled it with the gas at 1.10 and 23.0 and weighed it again. The difference in mass was 1.27 . Identify the gas. Express answer as a chemical formula
