(MW: 28.0131 g/mol). at standard temperature and pressure. The TA found that 146 mL of gas was collected at 21.0 degree C and 0.968 atm. The TA determined the volume of this gas sample at STP (1.00 atm and 273 K) is ____ mL. Your answer should be expressed with...

The ideal gas law (PV=nRT) describes the relationship among pressure P, volume V, temperature T, and molar amount n. Fix n and V When n and V are fixed, the equation can be rearranged to take the following form where k is a constant: PT=nRV=k or (PT)initial=(PT)final This demonstrates that for a container of gas held at constant volume, the pressure and temperature are directly proportional.The relationship is also called Gay-Lussac's law after the French chemist Joseph-Louis Gay-Lussac, one of...

chpt.9 pg 11: Pressure and temperature affect the amount of space between gas molecules, which affects the volume and, therefore, the density of the gas since density=massvolume The molar mass of a substance, however, is a constant and can be used to identify an unknown gas sample. Molar mass is found by dividing the mass of a sample (in grams) by the number of moles in that sample. The number of moles of gas can be calculated using the ideal...

Gas storage containers are sometimes designed to store the gas at a low temperature. This allows more gas to be stored at a lower pressure, and therefore more safely. Consider a rigid (constant volume) gas container that can safely store nH moles of gas at a higher temperature TH = 316 K and pressure PH = 5.02 x 10^6 Pa. Calculate the number of moles of gas, nL, that this container can hold at a lower temperature TL = 121...

The density of oxygen gas at a given temperature and pressure is 1.30 gL. The volume of 21.0 ml of O2 is effused from a device for 1,000 s. When the same device is used under the same conditions, the effusion rate of an unknown gas is 15.0 mL / s. What is the density of the unknown gas? Answer:2.55g/L
