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 ...
Vapor pressure formulas There are many different formulas, thanks to which you can calculate the vapor pressure of water. The most well-known and established is the Antoine equation, but other methods also exist (and they perform better in typical conditions). In our calculator, you'll find im...

Answer to: The vapor pressure of water at 100.0 degrees C is: (a) 175 torr. (b) 85 torr. (c) 760 torr. (d) 1 torr. (e) More information is needed...
Why does the vapor pressure of water decrease when NaCl is added to it?Question:Why does the vapor pressure of water decrease when NaCl is added to it?Water:Water is a universal solvent as it is capable of dissolving a large number of chemical species in it. The solution of ...
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). Xsolvent=nwaternglucose+nwaterX_{\rm solvent} = \frac{n_...
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.A...
6.0 g of urea (molecular weight = 60) was dissolved in 9.9 moles of water. If the vapour pressure of pure water isp0, the vapour pressure of solution is View Solution The vapour pressure of water at room temperature is 30 mm of Hg. If the mole fraction of the water is 0.9, the va...
