Convert a pressure of 0.0248 mm Hg to the equivalent pressure in pascals (Pa).
drek231 [11]

Answer is 3.306 Pa.


<em>Explanation:</em>


This is a simple unit conversion problem.

1 atm = 760 mmHg = 101325 Pa


Hence,

    0.0248 mmHg = (101325 Pa / 760 mmHg) x 0.0248 mmHg

                           = 3.306 Pa


Pressure can be measured by using many units such as atm, Pa, torr, bar, cmHg, mmHg and so on.


The relationships among those units as follows

1 atm = 101325 Pa = 1.01325 bar = 760 torr, 760 mmHg = 76 cmHg
