A gas cylinder containing 6.38 mol of neon has a pressure of 491 mm Hg at 295 K. If 3.22 mol of helium is added to this cylinder,at constant temperature and volume,what will be the pressure in the cylinder?
A sample of gas contains four gases (He,Ne,Ar,and Xe)with the following partial pressures: He (43 mm Hg),Ar (835 mm Hg),and Xe (111 mm Hg). If the total pressure in the container is 1355 mm Hg,what is the partial pressure of Ne in the sample?
Atmospheric pressure in interstellar space is approximately 1 × 10-17 torr at a temperature of -173 °C. How many gas molecules are present in 25,000 L of interstellar space (about the volume of a bedroom)?
An aerosol spray can with a volume of 350 mL registers a pressure of 4.5 atm at room temperature. What happens to the pressure of the gas inside the can if the can is stored outside during the winter months?
Hydrogen peroxide decomposes to give water and oxygen gas according to the equation below. If 3.0 moles of hydrogen peroxide decompose,what volume of oxygen gas is produced at a pressure of 1.0 atm and a temperature of 23 °C? 2 H2O2(l)→ 2 H2O(l)+ O2(g)
A gas cylinder containing 3.88 mol of helium has a pressure of 549 mm Hg at 298 K. If 1.22 mol of neon is added to this cylinder,at constant temperature and volume,the pressure will rise to 1750 mm Hg.
