Use the References to access important values if needed for this question. A 1.96 gram sample of an unknown gas is found to occupy a volume of 1.92 L at a pressure of 527 mm Hg and a temperature of 58 "C. The molecular weight of the unknown gas is Assume ideal behavior. questo remaining g/mol.
Use the References to access important values if needed for this question. A 1.81 mol sample of O₂ gas is confined in a 43.3 liter container at 18.8 °C. If the temperature of the gas sample is increased to 38.8 °C, holding the volume constant, the pressure will increase because: Choose all that apply. At higher temperatures molecules have higher average speeds. with lower average speeds, the molecules hit the walls of the container less often. As the number of molecule-wall collisions increases, the force per collision decreases. with higher average speeds, on average the molecules hit the walls of the container with more force. None of the Above
