How many moles of gas are in a container that has a volume of 20.5 mL, temperature of 303 K, and pressure of 1.10 atm? Assume ideal gas behavior. L atm L kPa • Use R-0.08206 mol K vor 8.314 v for the ideal gas constant. mol K • Your answer should have three significant figures.
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...
Calculate the volume of the gas when the pressure of the gas is 2.00 atm at a temperature of 298 K. There are 110. mol of gas in the cylinder. The value for the universal gas constant R is 0.08206 L⋅atm/(mol⋅K) . Express your answer numerically to four significant figures.
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. The van der Waals equation...
Learning Goal: To apply the ideal gas law to problems involving temperature, pressure, volume, and moles of a gas. The four properties of gases (pressure P, volume V, temperature T, and moles of gas n) are related by a single expression known as the ideal gas law: PV=nRT The variable R is known as the universal gas constant and has the value R=0.0821 L⋅atm/(mole⋅K). The units of R dictate the units for all other quantities, so when using this value...
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...
