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.

WebProblem #13:Calculate the volume 3.00 moles of a gas will occupy at 24.0 °C and 762.4 mm Hg. Solution: Rearrange the Ideal Gas Law to this: V = nRT / P Substitute values into the equation: V = [(3.00 mol) (0.08206 L atm mol¯1K¯1) (297.0 K)] / (762.4 mmHg / 760.0 mmHg atm¯1) Note the conversion from mmHg to atm in the denominator. WebI'd imagine that if a balloon were filled with one mole of hydrogen (H2) gas and one mole of, say, neon gas, that each neon atom would contribute to the total pressure more than each hydrogen molecule since the momentum of a neon atom would be 10 times greater than a hydrogen atom moving at the same speed (a neon atom is 10 times more massive than …
