As a result of air at the top of a barometer, the height of the mercury column is 73.5cm when it should be 75.0cm; the volume of the space above the mercury is 8.0cm3. Calculate the correct barometer height when the barometer reads 74.0cm and the volume of the space above the mercury is 6.0cm3.

Correct Answer: Option D
Explanation:
Using, P1P1 = P2P2
(75 - 73.5) x 8 = (X - 74) x 6
X = 76cm
Using, P1P1 = P2P2
(75 - 73.5) x 8 = (X - 74) x 6
X = 76cm
