TABLE 2.18<br />

Molar Equivalent of One Liter of Gas at Various Temperatures and Pressures<br />

The values in this table, which give the number of moles in 1 liter of gas, are based on the properties of an<br />

“ideal” gas and were calculated by use of the formula:<br />

P 273 1<br />

Moles/liter <br />

760 T 22.40<br />

where P is the pressure in millimeters of mercury and T is the temperature in kelvins (tC 273).<br />

To convert <strong>to</strong> moles per cubic foot multiply the values in the table by 28.316.<br />
