Final answer:
To convert 8.4 atm to mmHg and torr, multiply by 760 resulting in a pressure of 6384 mmHg and 6384 torr, as 1 torr equals 1 mmHg.
Step-by-step explanation:
To convert the pressure at an ocean depth of 76.2 m, which is about 8.4 atm, into mmHg and torr units, we use the conversion factor 1 atm = 760 mmHg = 760 torr. For the presented example, the calculation would be:
Pressure in mmHg = 8.4 atm × 760 mmHg/atm = 6384 mmHg
Since 1 torr is exactly equivalent to 1 mmHg, this also means that:
Pressure in torr = 6384 torr
Thus, the pressure at an ocean depth of 76.2 m, when expressed in mmHg and torr, is 6384 mmHg and 6384 torr, respectively.
