Answer to Question #188193 in Chemistry for amman

Question

The vapor pressure of solid iodine at 25°C is 1.42mmHg. Calculate the vapor pressure in atm and torr. Round each of your answers to 3 significant digits.

Answer 1

The vapor pressure in atm:

1 mmHg = 0.00132 atm

p = 1.42 mmHg = 1.42 × 0.00132 atm = 0.00187 atm

The vapor pressure in torr:

1 mmHg = 1 torr

p = 1.42 mmHg = 1.42 torr

Answer: 0.00187 atm; 1.42 torr
