Question
The vapor pressure of ethanol at 25°C is 0.0773atm.
Calculate the vapor pressure in mmHg and torr. Round each of your answers to 3 significant digits.
- mmHg:
- torr:
Solution
To convert the vapor pressure of ethanol from atm to mmHg and torr, we need to use the conversion factors.
1 atm = 760 mmHg = 760 torr
Step 1: Convert atm to mmHg 0.0773 atm * 760 mmHg/1 atm = 58.748 mmHg
Step 2: Round to 3 significant digits 58.748 mmHg ≈ 58.7 mmHg
Step 3: Convert atm to torr 0.0773 atm * 760 torr/1 atm = 58.748 torr
Step 4: Round to 3 significant digits 58.748 torr ≈ 58.7 torr
So, the vapor pressure of ethanol at 25°C is approximately 58.7 mmHg and 58.7 torr.
