One mole of any gas at 000ec (273 k) and 100 atm (760 torr) occupies a volume of 224 l these conditions are called standard temperature and pressure , or stp , and 224 l is called the standard molar volume. Molar volume of a gas is defined as the volume of one mole of the gas thus, the molar volume is also the volume occupied by 602 x 10 23 particles of gas the molar volume of any gas is 224 dm 3 mol -1 at stp or 24 dm 3 mol -1 at room conditions. R is the molar gas constant, where r=0082058 l atm mol-1 k-1 the ideal gas law assumes several factors about the molecules of gas the volume of the molecules is considered negligible compared to the volume of the container in which they are held.

Experiment 13: calcium carbonate analysis molar volume of carbon dioxide abstract: the goal of this experiment was to determine the percent calcium carbonate in a heterogeneous mixture and to determine the molar volume of carbon dioxide gas at 273 k and 760 torr. 8 collect the gas until no further reaction is observed in the reaction flask 9 carefully remove the gas collection flask so that no gas escapes from the flask 10 light the gas 11 determine the volume of the gas 12 calculate the molar volume of h2 gas at room temperature a) theoretical value from vm =2244 l/mol at stp.
A graphic illustration and a calculation of the approximate molar volume of nitrogen gas. Where p is the pressure of the gas, t is its temperature, and _ is its molar volume in the case of an ideal gas, the compressibility factor z is equal to unity, and the familiar ideal gas law is recovered. Archer g11 10 november 2011 determining the molar volume of a gas purpose: the purpose of this lab is to determine the molar volume of h 2 at room temperature and standard pressure.
Introduction: it is not necessary when finding the molar volume, to weigh one mole oxygen at 273k and 1013x 100000pa weighing such a large volume would be difficult and wasteful, and how long would you have to wait for a day on which the exact conditions of stp happen to occur. It is quite possible for the partial molar volume to be negative, as it would be at ii in the above diagram for example, the partial molar volume of magnesium sulphate in water is -14cm3 mol-1 ie addition of 1 mol mgso4 to a large volume of water results in a decrease in volume of 14 cm3. Molar volume is the volume that one mole of gas occupies when temperature and pressure are kept constant the molar volume of a gas can be determined through evaluating how much gas is given off when the number of moles of the substance is known. (1) you can use the ideal gas equation, pv = nrt, to find the volume of 1 mole of ideal gas (molar volume of gas) at 100 kpa and other temperatures (2) prior to 1982, standard temperature and pressure were defined as 0°c (27315 k) and 1 atm (1013 kpa), so 1 mole of gas would occupy a volume of 2241 l.
