A 3.78 gram sample of methane gas has a volume of 847 milliliters at a pressure of 2.17 atm. The temperature of the CH4 gas sample is °C. Hint PV = nRT R = 0.0821
A 1.75 L volume of helium gas stored at 0.873 atm will have a temperature of 46.9oC. If the helium is compressed down to a volume of 523 mL while allowing the pressure to settle at 1,662 mmHg, what will the temperature of the helium gas now be, in oC? Give your answer to one decimal place, and in units of oC. Data: 1 atm = 760 mmHg, 0oC = 273 K, PV = nRT, R = 0.0821 L.atm.mol-1.K-1.
A sample of gas at 760 torr and 2.8 L is compressed at constant temperature to the pressure at 3.5 atm. What is the final volume of the gas? My biggest problem with answering this question is the fact that I don't know what the "constant temperature" is..I know I'm using the combined gas law with formula: V2= p1v1/t1p2 * T2 and that p1=760 torr or 1 atm, v1=2.8L and p2=3.5 atm... Any help on this is very much appreciated.
For a certain amount of gas at constant temperature, the pressure and volume have an inverse relationship (Figure 1). This is called Boyle's law: P1V1=P2V2 A. A sample of ideal gas at room temperature occupies a volume of 33.0 L at a pressure of 862 torr . If the pressure changes to 4310 torr , with no change in the temperature or moles of gas, what is the new volume, V2? B. If the volume of the original sample in...
A sample of helium gas has a volume of 6.70 L at a pressure of 845 mmHgand a temperature of 26 ∘C . What is the final pressure of the gas, in atmospheres, when the volume and temperature of the gas sample are changed to the following, if the amount of gas does not change? 1550 mL and 315 K P1 = atm Part B 2.45 L and 18 ∘C P2 = atm Part C 14.0 L and 42 ∘C...
1- A gas sample has a pressure of 1.17 bar. What is this pressure in atm? Hint: 1 atm = 101.3 kPa = 1.013 bar = 760 torr = 760 mm Hg = 14.7 psi 2- A sample of gas has a volume of 474 mL at a pressure of 3.49 atm. The gas is compressed and now has a pressure of 7.72 atm. Predict if the new volume is greater or less than the initial volume, and calculate the...
