For a solution It says; VAPOR DENSITY: 1.3

Is VAPOR DENSITY the same as Density of that solution? And what is the unit of 1.3?

 

Hope for inputs.

 

 

Thanks.

The vapor density of a gas is the mass of a given volume of gas, divided by an equal volume of a reference gas (usually hydrogen) at the same temperature and pressure.

 

If it's 1.3 then I can only presume that it is 1.3 times heavier that the same volume of hydrogen gas at the same temperature and pressure.

 

Note: vapor density only applies when your solution is in the gas phase so if you are leaving it as a liquid then it doesn't apply to you.

I had always believed that it was in reference to atmospheric gases. Otherwise, every gas would have a vapor density greater than 1.
