The student from question 3 then heated the beaker of water and found that at 75 °C the corrected volume of the bubble was 4.05 mL. What should she report as the vapor pressure of water PH2O) at this temperature? Answer from question 3= 0.000095 moles of trapped air This was also the question for 3 just in case you needed it for information: A student found that at 755 torr atmospheric pressure and 0.2 °C, the corrected volume of the trapped air was 2.15 mL. Under these conditions, how many moles of trapped air nair are present?
Consider the following reaction taking place at constant T and V: N2(g) + 3 H2(g) → 2 NH3(g) You have a mixture of 235 torr of N2 and 633 torr of H2. When the reaction goes to completion, there is no Hydrogen left over and the Partial Pressure of NH3 is 422 torr. What will be the Partial Pressure (in torr) of unreacted (excess) N2?
The rate of effusion of NO2 gas through a porous barrier is observed to be 3.05 x 10-4 mol/h. Under the same conditions, the rate of effusion of CO₂ gas would be mol/h.
In a 0.5 L container of gas at sea-level where the temperature is 298 K, the collision rate between molecules, Z, is 1.2 x 104 s. If the collision cross-section, o, of 9 × 10-19 m² remains unchanged, what is the change in collision rate if the temperature is cooled to 170 K? Note: the relative average speed is assumed to remain unchanged. 17

The rate of effusion of a particular gas was measured and found to be 26.0 mL/min. Under the same conditions, the rate of effusion of pure methane () gas is 47.8 mL/min. What is the molar mass of the unknown gas? Mass = g/mol
Use the References to access important values if needed for this question. The rate of effusion of Kr gas through a porous barrier is observed to be 5.41 x 10-4 mol/h. Under the same conditions, the rate of effusion of Os gas would be mol/h.
The rate of effusion of a particular gas was measured and found to be 26.9 mL/min. Under the same conditions, the rate of effusion of pure methane () gas is 47.8 mL/min. What is the molar mass of the unknown gas?
