Question

The vapor pressure of water at 50.0 c is 12.33 kpa. What is this value in millimeters of mercury?

Answer 1

• 92.48 mmHg

Step-by-step explanation:

You need the conversion factor to convert the value of 12.33 kPa to milimiters of mercury, mmHg.

The converstion factors are looked at tables, which today you can find in internet.

Since the conversions between kPa and atm and between atm and mmHg are more widely known, I will show the conversion using those relations:

• 1 atm = 101.325 kPa

• 1 atm = 760 mmHg

⇒ 101.325 kPa = 760 mmHg

Then, dividing both sides by 101.325 kPa you get the conversion factor:

• 1 = 760 mmHg / 101.325 kPa

Now, multiply 12.33 kPa by that conversion factor:

• 12.33 kPa × 760 mmHg / 101.325 kPa = 92.48 mmHg ← answer
