for STP – standard temperature and pressure (273.15 K, 101.325 kPa) – the molar volume of an ideal gas is 22.413962x10-3 m3 mol-1 with standard uncertainty 0.000013 x 10-3 m3 mol-1.2
The limiting procedures under which the behaviour of the van der Waals gas approaches that of an ideal gas are letting two van der Waals coefficients be zero rather than letting the molar volume become infinitely large; otherwise, the partial derivative of internal energy with respect to pressure...
The ideal gas law is an approximation used to show how gases respond to changes in their pressure, temperature, and volume. The ideal gas law formula is PV = nRT. This formula can be used to calculate any of the parameters shown in the equation. It can also be used to calculate the ...

The partial molar volume of a liquid is the net volume change when one mole of the liquid is added to a large excess of a pure liquid or a mixture. From: Physical Chemistry, 2017 About this pageSet alert Discover other topics On this page Definition Chapters and Articles Related Terms Rec...
The molar volume of a gas, V, is found using the formula for the ideal gas law: PV = nRT. In this equation, P is pressure, n is 1 mol, R is the universal gas constant, and T is the temperature in Kelvin. The value for R will vary depending on the units of pressur...
The molar gas volume means the fixed volume of one mole of any gas at a specific temperature and pressure. It is expressed as the ratio between the molar mass (M) and mass density (ρ). It is also called the molar volume of the gas....
However, compared to the known value of 46.1 g of ethanol, the value measured had a 108% error. Unfortunately, this was a very big percent error and may have been caused by incorrectly measuring the volume of the gas. Using the ideal gas law, the molar mass of a volatile compound was...
At 68.0 °C and 893 torr, find the molar mass of a gas that has a volume of 12.4 mL and mass of 178 mg.
