A) A sample of oxygen gas at a pressure of 0.680 atm and a temperature of 22.0 °C, occupies a volume of 16.4 liters. If the gas iscompressed at constant temperature to a volume of 7.95 liters, the pressure of the gas sample will be__________ atm. B)A sample of oxygen gas at a pressure of 878 mm Hg and a temperature of 65 °C, occupies a volume of 6.95 liters. If the gas isheated at constant pressure to a temperature...
A sample of oxygen gas collected at a pressure of 0.905 atm and a temperature of 278 K is found to occupy a volume of 651 milliliters. How many moles of O2 gas are in the sample?
At 283 K and a total equilibrium pressure of 0.989 atm, the fractional dissociation of NO is 0.363 for the reaction 2NO(g)N2(g) + 02(g) This means that 363 of every 1000 molecules of NO originally present have dissociated. Calculate the equilibrium constant in terms of pressures, Kp. Kp

A sealed 33 m3 tank is filled with 3000 moles of ideal oxygen gas (diatomic) at an initial temperature of 270 K. The gas is heated to a final temperature of 380 K. The atomic mass of oxygen is 16.0 g/mol. The initial pressure of the gas, in MPa, is closest to: 0.18 0.15 0.20 0.26 0.23
Helium atoms have a mass of 4u and oxygen molecules have a mass of 32u, where u is defined as an atomic mass unit (u=1.660540×10?27kg). Compare a gas of helium atoms to a gas of oxygen molecules. At what gas temperature Trms would the root-mean-square (rms) speed of a helium atom be equal to that of an oxygen molecule in a gas at 300 K? The answer is not 300 or 37.5

A sample of argon gas at 303 K and 2.25 atm occupies a volume of 2.65 L. If the gas is allowed to expand to a larger volume, while at the same time it is cooled to a lower temperature, the final gas pressure will be higher than 2.25 atm could be higher or lower than 2.25 atm depending on the final volume and temperature. will be lower than 2.25 atm A sample of oxygen gas at 301 K and...
A sample of oxygen has a volume of 450 mL when its pressure is 1.2 atm. What will the volume of the gas be at a pressure of 1.15 atm if the temperature remains constant?
