Question

The barometer indicates the pressure is 1520.0 mm hg. what is this pressure expressed in atmospheres?

Answer 1

To convert the pressure from millimeters of mercury (mmHg) to atmospheres (atm), we can use the conversion factor:

1 atm = 760 mmHg

So, to convert 1520.0 mmHg to atm, we divide it by 760:

1520.0 mmHg / 760 mmHg/atm = 2.0 atm

Therefore, a barometer reading of 1520.0 mmHg is equivalent to 2.0 atmospheres (atm).
