Using his extensive measurements of the properties of gases, [6] [7] Mendeleev also calculated it with high precision, within 0.3% of its modern value. [ 8 ] The gas constant occurs in the ideal gas law: P V = n R T = m R s p e c i f i c T {\displaystyle PV=nRT=mR_{\rm {specific}}T} where P is the absolute pressure , V is the volume of gas, n ...
There is a 1:1 molar ratio of NH 3 to NO 2 in the above balanced combustion reaction, so 5.871 mol of NO 2 will be formed. We will employ the ideal gas law to solve for the volume at 0 °C (273.15 K) and 1 atmosphere using the gas law constant of R = 0.08206 L·atm·K −1 ·mol −1:
Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...
Here because is a multivalued function, the integral must be divided into 3 parts corresponding to the 3 real roots of the vdW equation in the form, (,) (this can be visualized most easily by imagining Fig. 1 rotated ); the result is a special case of material equilibrium. [62]
It is the world's largest and most widespread religion with over 2.38 billion followers, comprising around 31.2% of the world population. [10] Its adherents, known as Christians , are estimated to make up a majority of the population in 157 countries and territories .
