A gas of unknown molecular mass was allowed to effuse through a small opening under constant pressure conditions. It required 72 s for 1.0 L of the gas to effuse. Under identical experimental conditions it required 27 s for 1.0 L of 02 gas to effuse. Calculate the molar mass of the unknown gas. (Remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0 L; that is, rate and time are inversely proportional.) 367.1175859 X g/mol
A sample of an unknown gas with a mass of 1.620g occupied a volume of 941mL when its pressure was 748 torr and its temperature was 20.00 oC. When made to decompose into its elements, 1.389g of carbon and 0.2314g of hydrogen were obtained. 1. What is the percentage composition of the elements in this gas? 2. Determine its empirical formula. 3. Determine its molecular formula.
2. Sodium sulfide (0,1159 g) and excess hydrochloric acid were reacted together to form 35.75 mL of an unknown gas. The gas was collected over water when the atmospheric pressure was measured to be 767 mmHg. The temperature of the water was 23.0°C. Determine the molar mass, as well as identity, of the gas.

Argon gas exerts 1.06 atm pressure at 290 K. Determine its density in g/L.
Match the characteristic of gases described below to the postulates of the kinetic molecular theory that best explain that characteristic. (Note: You may need to list more than one postulate.) The pressure of a gas in a fixed volume increases when its temperature increases. Select one or more: The average kinetic energies of gas particles increase with an increase in temperature. Gas particles are widely spaced. A gas consists of many small particles in rapid, random motion. The total volume of the molecules themselves is very small compared to the volume of the container. There are virtually no attractive forces between gas particles.
3) A chemist decomposes 1.06 g of NO, at 35°C in a sealed system. The gas produced has a pressure of 0.514 atm. Calculate the gas volume required.
Use the kinetic molecular theory of gases to predict what would happen to a closed sample of a gas whose temperature increased at constant volume. The average kinetic energy of the gas particles would increase. Pressure would decrease. Pressure would be constant. The number of moles of gas would decrease.
