Solution: A barometer tube is 1.00×102 cm long and has a cross-sectional area of 1.20 cm 2. The height of the mercury column is 74.0 cm, and the temperature is 24°C. A small amount of N2 is introduced into the evacuated space above the mercury, which causes the mercury level to drop to a height of 64.0 cm. How many grams of N2 were introduced?
