To identify a diatomic gas (X_2) a researcher carried out the following experiment: She weighed an empty 1.3-L bulb, then filled it with the gas at 1.60 atm and 30.0 degree C and weighed...
chpt.9 pg 11: Pressure and temperature affect the amount of space between gas molecules, which affects the volume and, therefore, the density of the gas since density=massvolume The molar mass of a substance, however, is a constant and can be used to identify an unknown gas sample. Molar mass is found by dividing the mass of a sample (in grams) by the number of moles in that sample. The number of moles of gas can be calculated using the ideal...

Page 3 of 3 Gas Density and Molar Mass 9. The density of a diatomic gas is 1.634 g/L at 1.50 atm and 40.0°C. Calculate the molar mass of the gas, and use the periodic table to identify the gas. (10 pts)
please help! Consider a process carried out on 1.00 mol of a monatomic ideal gas by the following two different pathways. The first pathway is A (3.00 atm, 20.0 L) to C (1.00 atm, 20.0 L) to D (1.00 atm, 50.0 L): and the second pathway is A (3.00 atm, 20.0 L) to B (3.00 atm, 50.0 L) to D (1.00 atm, 50.0 L). In each case, the gas is taken from state A to state D. Calculate AHABD 475...
