A radio station announcer reports the atmospheric pressure to be 99.6 kPa. What is the pressure in atmospheres? In millimeters of mercury?
Solution
Look up conversions factors in a table to convert between kilopascals and atmospheres and millimeters of mercury. Use a conversion factor approach to solve the problem:
99.6 kPa x 1 atm/101.3 kPa = 0.983 atm
0.983 atm x 760 mm Hg/1 atm = 747 mm Hg
Answer
0.983 atm; 747 mm Hg
