What is the relation between the density of vapor and the

AI Thread Summary
The discussion centers on the relationship between the density of vapor, mass, and temperature of alkali metals when they are vaporized. The ideal gas law, represented by the equation PV=nRT, is highlighted as a key tool for understanding this relationship. In this equation, pressure (P) is directly proportional to the number of moles of gas (n) and the absolute temperature (T), while being inversely proportional to the absolute volume (V). This indicates that as temperature increases, pressure also increases if volume remains constant, which is crucial for analyzing the behavior of vaporized alkali metals.

hi guys

my question is

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.

sorry, can u explain how ??
 
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?

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
