To convert from atmospheres (atm) to millimeters of mercury (mm Hg), you can use the conversion factor that 1 atm is equal to 760 mm Hg.
Given that 0.45 atm is the starting value, we can multiply it by the conversion factor of 760 mm Hg/atm:
0.45 atm * 760 mm Hg/atm = 342 mm Hg
Therefore, 0.45 atm is equal to 342 mm Hg.Answer:
