The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles ( n): PV = nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van der Waals equation corrects for these factors with the constants a and b, which are unique to each substance: (P+ ²) (V-nb) = nRT an² The gas constant R is equal to 0.08206 L.atm/(K-mol). Part A A 3.00-L flask is filled with gaseous ammonia, NH3. The gas pressure measured at 16.0 °C is 2.45 atm . Assuming ideal gas behavior, how many grams of ammonia are in the flask? Express your answer to three significant figures and include the appropriate units. View Available Hint(s) mass of NH3 = Submit ▾ Part B HÅ…
Starting with Charles's law (stated as an equation), obtain an equation for the final volume of a gas from its initial volume when the temperature is changed at constant pressure. From Charles's law, VT = constant Because this is true for initial conditions as well as for final conditions, we can write V. V; T T; Thus, the equation for the final volume is P.V = P;V; Drag and drop your selection from the following list to complete the answer: P T; V, = V, x Pr PV = constant V = constamt T VT = V;T, V, = V, x T = constant V. P;V; P V, = V, x P, PV = constant T T
If pressure is expressed in atmospheres and volume is expressed in liters, PAV has units of L atm (liters x atmospheres). Remember that 1 atm 101,325 Pa, and that 1 L = 1 dm³. Use this information to determine the number of joules corresponding to 2L atm. eTextbook and Media Savo for Lotor
A mixture of Oxygen and Chlorine gases contain twice as much Oxygen (by mass - in grams) as Chlorine (2xO2g= Cl2g) If the total pressure of the mixture is 565mmHg, then what is the partial pressure of chlorine ? Using (from Ideal Gas law - Dalton) Partial Pressure Partial Pressure (?) Moles of Chlorine (?) / (divided) by Total Moles O2+Cl2 or written nA / nT (Total Pressure) I've tried to determine what multiple of Oxygen, in grams - by atomic mass, will give me 1/2 the weight of Chlorine - in order to determine Mole (mol) Count for each DIATOMIC. I'm not frustrated, but i'm a little tired of going through this, for 2 hours, I have looked at - similar formula - variations, but this is the challenge. thanks
A sample of oxygen gas was found to have a pressure of 94kPa when the temperature was 19°C. What can its pressure be, in kPa , expected to be if the temperature is 12.5°C? Round off your answer to 2 decimal values
100% EXP 3- Determination of universal gas constant Thermal decomposition reaction of KCIO3 can be used to determine the universal gas constant. 2KCIO:(s) 2KCI(s) + 302(g) MnO2 (catalyst) Firstly, KCIO3 and MnO2 (catalyst) is placed in a clean and dry test tube, and it is weighed as 15.92 g. While heating the test tube, thermal decomposition reaction occurs and all the evolved O2(g) is collected in a flask filled with water at 759 mmHg and 20°C. Because of evolved O2(g), 250 mL water is transferred from the flask to a beaker. Additionally, the weight of test tube after heating is determined as 15.60 g. (Note: The partial pressure of water at 20°C is 17.5 mmHg.) (a) Calculate experimental value of the universal gas constant by using the information given above. (b) Compare the theoretical and the experimental values of gas constant and calculate the percentage error in the experiment. (KČIO:: 122.55 g/mol. Oz: 32.00 g/mol, R: 0.082 L atm/mol K) EXP 4- Diffusion
Sketch three isochores for the same gas at three different volumes V1, V2 and V3 where V1 = V3 and V2<V3. How the temperature scale (K vs oC) will change on your plot?
5. There are 1.07 X 103 moles of gas molecules contained in a CO2 cartridge under 5.0-atm of internal pressure. After several uses, the internal pressure is 3.4-atm. How many moles of gas remain in the cartridge? How much gas will remain in the cartridge when the internal pressure equilibrates to standard pressure? (Assume that the temperature and volume remain constant.)
The ideal gas law is a limiting law, in that it is expected to hold as pressure approaches zero. Suppose the following measured values have been obtained for oxygen gas at 273.15K. Based on the data, calculate R for each pressure value and create a table of pressure and R values (i.e. you are treating R as a variable rather than a constant at this point). Then create a plot R vs p and find the “best value” of R by determining the y-intercept of a straight line fit. (Be sure to label your axes including units).
1. The compressibility factor Z = PV/nRT for O2 at -27.1°C and 537.1 atm is 1.50; at 147.4°C and 95.5 atm, it is 1.02. A certain mass of oxygen occupied a volume of 3.28 L at 147.4°C and 95.5 atm. Calculate the volume occupied by the same quantity of oxygen at -27.1°C and 537.1 atm. 2. The composition of a mixture of gases in percentage by volume is 20.5% nitrogen, 15.7% carbon monoxide, 37.8% water, and the rest sulfur dioxide. Calculate the density of the gaseous mixture at 39.8°C and 1.46 atm in grams/liter. Report your answer to the hundredths position.
