question Posted March 25, 2005 Share Posted March 25, 2005 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. Link to comment Share on other sites More sharing options...
dan19_83 Posted March 25, 2005 Share Posted March 25, 2005 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. Link to comment Share on other sites More sharing options...
jdurg Posted March 25, 2005 Share Posted March 25, 2005 I had always believed that it was in reference to atmospheric gases. Otherwise, every gas would have a vapor density greater than 1. Link to comment Share on other sites More sharing options...
