A gas sample containing 1.50 moles at 25oC exerts a pressure of 400. torr. Some gas is added to the same container, and the temperature is increased to 50oC. If the pressure increases to 800. torr, how many moles of gas were added to the container? Assume a constant- volume container.
Answer to relevant QuestionsConsider the following chemical equation: 2NO2(g) → N2O4(g) If 25.0 mL of NO2 gas is completely converted to N2O4 gas under the same conditions, what volume will the N2O4 occupy? Consider the flasks in the following diagrams. a. Which is greater, the initial pressure of helium or initial pressure of neon? How much greater? b. Assuming the connecting tube has negligible volume, draw what each diagram ...Given that a sample of air is made up of nitrogen, oxygen, and argon in the mole fractions 78% N2, 21% O2, and 1.0% Ar, what is the density of air at standard temperature and pressure? A sample of methane (CH4) gas contains a small amount of helium. Calculate the volume percentage of helium if the density of the sample is 0.70902 g/ L at 0.0oC and 1.000 atm. At elevated temperatures, sodium chlorate decomposes to produce sodium chloride and oxygen gas. A 0.8765-g sample of impure sodium chlorate was heated until the production of oxygen gas ceased. The oxygen gas collected over ...
