PV nRT beginarraylRightarrow RfracPVnTendarray Where P is the pressure of the ideal gas. V is the Volume in Metre cubes. As per my knowledge PVmrT and PVnRT are often confused.

Specifically R is equal to the ratio PVnT. It is usually expressed as 008206 L x atmK x mol or 8314 JK x mol. PV nRT.

The Dobson unit DU is a unit of measurement of the amount of a trace gas in a vertical column through the Earths atmosphereIt originated and continues to be primarily used in respect to atmospheric ozone whose total column amount usually termed total ozone and sometimes column abundance is dominated by the high concentrations of ozone in the stratospheric. The exact numerical value of the gas constant actually varies with the chosen units. 62 liters of an ideal.

Hydrogen as example of diatomic molecule. A commercially sold conc. Hope you have learnt the value of R at atm along with the list of the values of R in various other units.

The volume of this amount of gas under the conditions of STP is known to a high degree of precision. For volume in liters temperature in degrees Kelvin and pressure in atmospheres its value is 00821 L atmK mol. Index Kinetic theory concepts Sears Salinger Sec 9-7.

I am assuming below that you are working in strict SI units as you will be if you are doing a UK-based exam for example. See Wikipedia Gas Constant for a table of R values and their corresponding units. 100 atm 192 L n 008206 273 K n 08570518 mol Ill keep a few guard digits 2 Determine the molecular weight.
