Answer

Explanation:

Step1: Recall pressure - conversion factor

The conversion factor from psi (pounds - per - square - inch) to mmHg (millimeters of mercury) is 1 psi = 51.715 mmHg.

Step2: Convert initial pressure

For the initial pressure of 220. psi, we multiply by the conversion factor: $220.\times51.715 = 11377.3$ mmHg. Rounding to 3 significant figures (since 220. has 3 significant figures), we get 11400 mmHg.

Step3: Convert pressure after 1 - week use

For the pressure of 49. psi after 1 - week use, we multiply by the conversion factor: $49.\times51.715=2534.035$ mmHg. Rounding to 2 significant figures (since 49. has 2 significant figures), we get 2500 mmHg.

Answer:

Part 1 of 2: 11400 mmHg Part 2 of 2: 2500 mmHg
