How does molar mass affect vapor pressure
WebAt 15 degress the vapor pressure of water is 12.8 mm Hg. So that does agree with your intuition. At 15 degrees, the vapor only creates a pressure of 12.8 mmg Hg while at 25 degrees, the vapor creates a pressure of 23.8 mm Hg. Meaning, at 25 degrees, more water vaporizes to create a greater pressure. Comment. WebNov 5, 2015 · Gas Pressure and Molecular Mass. The ideal gas equation (or the van der Waals equation, for this matter) states that holding volume and temperature constant, …
