997.65cmH2O

Explanation:

Barometric pressure = 739 mmHg

density of Hg = 13.5 g/ml

density of water (H2O) = 1.00 g/ml

Calculate Barometric pressure in centimetres of water (cmH20)

equate the barometric pressure of Hg and water

739 * 13.5 * 9.8 = x * 1 * 9.81

x (barometric pressure of water in mmH2O) = 739 * 13.5 / 1 = 9976.5mmH2O

in cmH2O = 997.65cmH2O
