Final answer:

The pressure on the body of a diver at 22 ft below the surface of the water, considering an atmospheric pressure of 737 torr, is approximately 1.64 ATA (atmospheres).

Step-by-step explanation:

To calculate the pressure on the body of a diver who is 22 ft below the surface of the water, we can use the fact that every 33 feet of salt water represents 1 ATA (atmosphere absolute) of pressure in addition to the 1 ATA of pressure from the atmosphere at sea level. Since the diver is at 22 ft, which is less than 33 ft, the pressure from the water will be less than 1 ATA. Firstly, we convert the atmospheric pressure from torr to atmospheres, knowing that 1 atm = 760 torr, and then add the additional pressure from the water depth.

Atmospheric pressure at sea level = 737 torr / 760 torr/atm = 0.97 atm (approx.)

Pressure due to water depth = (22 ft / 33 ft) × 1 ATA

Total pressure experienced by the diver = Atmospheric pressure + Water pressure = 0.97 atm + (22 / 33) × 1 ATA = 0.97 atm + 0.67 ATA = 1.64 ATA (approx.)
