As a result of air at the top of a barometer, the height of the mercury column is \(73.5 \mathrm{~cm}\) when it should be \(75.0 \mathrm{~cm}\); the volume of the space above the mercury is \(8.0 \mathrm{~cm}^{3}\).
Calculate the correct barometric height when the barometer reads \(74.0 \mathrm{~cm}\) and the volume of the space above the mercury is \(6.0 \mathrm{~cm}^{3}\).
A. \(72.0 \mathrm{~cm}\) B. \(74.5 \mathrm{~cm}\) C. \(75.1 \mathrm{~cm}\) D. \(76.0 \mathrm{~cm}\)
