WebScience Advanced Physics A container with volume 1.64 L is initially evacuated. Then it is filled with 0.226 g of N2. Assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy. If the root-mean-square speed of the gas molecules is 182 m/s, what is the pressure of the gas? WebStirring was employed to dissolve the base, and the tube containing the ketone and PhI was cooled with a dry ice acetone bath The system was evacuated and filled with nitrogen. This procedure was repeated 3-8 times. After the freeze pump-thaw cycles were complete, the reactants were added to the flask by rotation of the bent tube.

WebQuestion: A container with volume 1.64 L is initially evacuated. Then it is filled with 0.241 g of N2. Assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy. If the root-mean-square speed of the gas molecules is 162 m/s, what is the pressure of the gas? Express your answer in pascals. WebQuestion: A container with volume 1.62 L is initially evacuated. Then it is filled with 0.254 g of N2. Assume that the pressure of the gas is low enough for the gas to obey the ideal-gas law to a high degree of accuracy. Part A) If the root-mean-square speed of the gas molecules is 162 m/s , what is the pressure of the gas? dc結合 ac結合 オシロスコープ
