Question
The vapor pressure of solid iodine at 25°C is 1.42torr. Calculate the vapor pressure in mmHg and atm. Round each of your answers to 3 significant digits.mmHgatm
Solution 1
The vapor pressure of solid iodine at 25°C is given as 1.42 torr.
-
Conversion from torr to mmHg: The conversion factor between torr and mmHg is 1, meaning 1 torr = 1 mmHg. Therefore, the vapor pressure in mmHg is also 1.42 mmHg.
-
Conversion from torr to atm: The conversion factor between torr and atm is approximately 0.00132, meaning 1 torr = 0.00132 atm. Therefore, to convert the vapor pressure to atm, we multiply the given pressure in torr by the conversion factor:
(1.42 torr) * (0.00132 atm/1 torr) = 0.00187 atm
So, the vapor pressure of solid iodine at 25°C is 1.42 mmHg and 0.00187 atm.
Solution 2
The vapor pressure of solid iodine at 25°C is given as 1.42 torr.
-
Conversion from torr to mmHg: The conversion factor between torr and mmHg is 1, meaning 1 torr = 1 mmHg. Therefore, the vapor pressure in mmHg is also 1.42 mmHg.
-
Conversion from torr to atm: The conversion factor between torr and atm is approximately 0.00132, meaning 1 torr = 0.00132 atm. Therefore, to convert the vapor pressure to atm, we multiply the given pressure in torr by the conversion factor.
1.42 torr * 0.00132 atm/torr = 0.0018744 atm
Rounding to three significant digits, the vapor pressure in atm is 0.00187 atm.

Calculate the change in enthalpy (amount of heat at constant pressure) when a mole of iodine goes from 300 K to 500 K under the pressure of one atmosphere. We give: the molar heat capacities of pure bodies: Cp (I2, solid) =22.6 J/mol K, Cp (I2, liquid) = 81.6 J/mol K Cp (I2, gas) = 37.7 J/mol K, ΔH°v(I2) at 457K = 25.52 kJ/mol, ΔH°F (I2) at 387K = 15.65 KJ/mol
