The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles (n): PV=nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van...

535 One mole of an ideal gas at 0°C and 1.00 atm pressure contains 6.022 x 10 molecules (Avogadro's number) and occupies a volume of 22.414 L. A good States of Matter...
Taking into account the vapor pressure of water, how many moles of hydrogen gas, n, are present in 343 mL at 752 torr and 29 ∘C?The value of the gas constant R is 0.08206 L⋅atm/(mol⋅K). You may also find the conversion factors 1 atm=760 torr and TK=TC+273 useful. Express the number of moles to three significant figures.
An engine using 1 mol of an ideal gas initially at 22.3 L and 454 K performs a cycle consisting of four steps: 1) an isothermal expansion at 454 K from 22.3 L to 40 L ; 2) cooling at constant volume to 270 K ; 3) an isothermal compression to its original volume of 22.3 L; and 4) heating at constant volume to its original temperature of 454 K . Find its efficiency. Assume that the heat capacity is...
The van der Waals equation gives a relationship between the pressure p (atm), volume V(L), and temperature T(K) for a real gas: .2 where n is the number of moles, R 0.08206(L atm)(mol K) is the gas con- stant, and a (L- atm/mol-) and b (L/mol) are material constants. Determine the volume of 1.5 mol of nitrogen (a .39 L2 atm/mol2. b = 0.03913 L/mol) at temperature of 350 K and pressure of 70 atm.
