3 Ways to Calculate Vapor Pressure - wikiHow
WebThe vapor pressure of a liquid varies with its temperature, as the following graph shows for water. The line on the graph shows the boiling temperature for water. As the temperature of a liquid or solid increases its vapor pressure also increases. Conversely, vapor pressure decreases as the temperature decreases. WebTranscribed image text: 12.1 Dry ice has a vapor pressure of 1 atm at - 72.2°C and 2 atm at - 69.1 °C. Calculate the AH of sublimation for dry ice. 12.2 The vapor pressure of liquid bromine at 9.3 °C is 100 Torr. If the heat of vaporization is 30 910 J/mol, calculate the boiling point of bromine. 12.3 The vapor pressure of diethyl ether is ... WebAug 31, 2024 · Solution From Table 1 we find that at 25°C the vapor pressure of water is 23.8 mmHg. Accordingly pH2 = ptotal – pH2O = 754 mmHg – 23.8 mmHg = 721.6 mmHg. This must be converted to units compatible R: p H 2 = 721 .6 mmHg × 1 atm 760 mmHg = 0 .949 atm The road map for this problem is m Zn → M Zn n Zn → S ( H 2 /Zn) n H 2 → R … shaping wooden table legs
