if you have few grams of alkali metals and vapored it , what is the mathematical equation that links between these variables density vapor , the mass and the temperture ??

can you help me ?

If the metal is hot enough to be in the gaseous state, you can treat it as an ideal gas.

You do know the ideal gas equation?

PV=nRT where:
P= absolute pressure
V= absolute volume
T= absolute temperature
n= number of moles of gas
R= universal gas constant (8.3145 J/mol*K)

From the equation, you can see that pressure (P) is directly proportional to the concentration or number of molecules (n) and the temperature of the system (T), and at the same time it is inversely proportional to the volume of the system, V. Does that help any?
