Question

What is the barometric pressure in atm if the typical reading in California is about 750 mmHg?

a) 0.986 atm
b) 1.013 atm
c) 0.987 atm
d) 1.000 atm

Answer 1

The barometric pressure in atm is 0.986.

Step-by-step explanation:

The barometric pressure can be converted from mmHg to atm using the conversion factor 1 atm = 760 mmHg. To calculate the barometric pressure in atm, divide the mmHg reading by 760. In this case, the typical reading in California is 750 mmHg, so the barometric pressure in atm would be 750 mmHg / 760 mmHg = 0.986 atm.
