CHEM 24112 Chapter Notes - Chapter 13: Combined Gas Law, Ideal Gas Law, Ideal Gas

The prevailing atmospheric pressure on a plateau in Colorado is 0.702 atm. Express this pressure in pounds per square inch, kilopascals, pascals, millimeters Hg, and inches Hg. A sample of neon gas at a pressure of 0.813 atm and a temperature of 26.4 degree C, occupies a volume of 18.2 liters. If the gas is compressed at constant temperature to a volume of 6.93 liters, the pressure of the gas sample will be atm. A sample of hydrogen gas occupies a volume of 9.74 L at 49 degree C and 0.547 atm. If it is desired to decrease the volume of the gas sample to 6.89 L, while decreasing its pressure to 0.346 atm, the temperature of the gas sample at the new volume and pressure must be degree C. A sample of argon gas collected at a pressure of 1.16 atm and a temperature of 282 K is found to occupy a volume of 674 milliliters. How many moles of Ar gas are in the sample? Mol A sample of an unknown gas is found to have a density of 1.63 g/L at a pressure of 1.08 atm and a temperature of 54 degree C. the molecular weight of the unknown gas is g/mol Assume ideal behavior. A mixture of oxygen and helium gases, in a 9.78 L flask at 90 degree C, contains 3.21 grams of oxygen and 1.08 grams of helium. The pressure of helium in the flask is atm and the total pressure in the flask is atm.

Which and a Assum has of gas to the cylinder? (Assume constant temperature and pressure.) ldeal Gas Law What is the volume occupied by 0.118 mol of helium gas at a m sure of 0.97 atm and a temperature of 305 K? Would the vol- ume be different if the gas was argon (under the same conditions)? 38. What is the volume occupied by 12.5 g of argon gas at a pres sure of 1.05 atm and a temperature of322 K? Would the volume be different if the sample were 12.5 g of helium (under identical conditions)? 39. What is the pressure in a 10.0 L cylinder filled with 0.448 mol of nitrogen gas at a temperature of 315 K? d0. What is the pressure in a 15.0 L cylinder filled with 32.7 g of oxygen gas at a temperature of 302 K? cylinder contains 28.5 L of oxygen gas at a pressure of 1.8 atm and a temperature of 298 K. How much gas (in moles) is in the cylinder? at is temperature of 0.52 mol of gas at a pressure of the atm and a volume of 11.8 L? automobile tire has a maximum rating of 38.0 psi The (while cold) to a volume of Land tire is inflated temperature its 120 gauge pressure of 36.0 psi at a 65.0 oC ing on a hot day, the tire warms to
