Answer: A. 101.3 kPa
Explanation:
By experiment, standard sea-level pressure = 760 mm (29.92 inches) of mercury, which also = 14.70 pounds per inch², which also = 1,013.25 × 103 dynes per cm², which also = 1,013.25 millibars, and one standard atmosphere = 101.325 kPa.
Therefore, the unit of pressure that represents the force exerted by the atmosphere at sea level is 101.3 kPa
