Question 8 • 26-27 - C - RUSD Chemistry in the Earth System

If the atmospheric pressure on the top of a mountain is 0 point 2 3 9 6 atm , what is the pressure in kilopascal kPa ?

Answer

422 point 9 kPa

2 point 3 6 5 times 10 to the negative 3 power kPa

24 point 2 8 kPa

182 point 1 kPa

Explanation

Use the conversion 1 atm = 101.325 kPa. Then 0.2396 atm × 101.325 kPa/atm ≈ 24.28 kPa, so the pressure is about 24.28 kPa. This matches choice C, 24.28 kPa.
