The vapor pressure of water has been measured in the range −2.5 to 20°C. The results are in good agreement with other experimental values, particularly those by Scheel and Heuse, but are higher than those in the International Steam Tables. A direct measurement of the triple-point ...
The vapor pressure of pure water at 25 °C is 23.8 torr. What is the vapor pressure of water above a solution prepared by dissolving 18.0 g of glucose (a nonelectrolyte, MW = 180.0 g/mol) in 95.0 g of water?A 24.3B 23.4C 0.451D 0.443E 23.8 相关知识点: 试题来源: 解析 B ...
The vapor pressure of water at 30.0 degrees C is 31.8 torr. Calculate the vapor pressure of water at 60.0 degrees C knowing that the heat of vaporization of water (Delta H_vap) is 43.9 kJ/mol. At 34.18 ^oC, the vapor pressure of wa...
Table 3.4 lists the equilibrium vapor pressure of water as a function of temperature. The boiling point is when the vapor pressure equals the ambient pressure. For water this is 100°C at 760 Torr. At about 22°C (room temperature) the equilibrium vapor pressure of water is about 20 Torr...
Good evening. Does anyone know of a table or perferable a formula for the calculation of the vapor pressure of saturated water vapor. This is for a pure water v
The vapor pressure of pure water at 25 °C is 23.8 torr. Determine the vapor pressure (torr) of water at 25 °C above a solution prepared by dissolving 35 g of urea (a non-volatile, non-electrolyte, MW = 60.0 g/mol) in 75 g of water.
Let's use this vapor pressure equation in an exercise: What is the vapor pressure of a solution made by dissolving 100 grams of glucose (C6H12O6) in 500 grams of water? The vapor pressure of pure water is 47.1 torr at 37 °C. Calculate the mole fraction of water (the solvent). Xso...
