Question

the vapor pressure of water at 5 °c is 0.00861 atm. calculate the vapor pressure in mmhg and torr. round each of your answers to 3 significant digits.

Explanation:

Step1: Convert atm to mmHg

Use conversion factor: $1\ \text{atm} = 760\ \text{mmHg}$.
Calculation: $0.00861 \times 760 = 6.5436$
Round to 3 significant digits: $6.54$

Step2: Convert atm to torr

Use conversion factor: $1\ \text{atm} = 760\ \text{torr}$ (1 torr = 1 mmHg).
Calculation: Same as mmHg result: $6.54$

Answer:

6.54 mmHg
6.54 torr
