Because water is 13.6 times less dense than mercury,an atmospheric pressure of 76 cm (30 in.)of mercury would be equivalent to 1034 cm (408 in.)of water.Therefore,a water barometer resting on the ground near sea level would have to be read from a ladder over ____ tall.
A)5 m (16 ft)
B)10 m (33 ft)
C)15 m (49 ft)
D)20 m (66 ft)
E)25 m (82 ft)

The atmospheric pressure equivalent to 76 cm of mercury is approximately 1034 cm of water, which is about 10.34 meters. Therefore, a water barometer would need to be read from a height of over 10 meters, which is closest to 10 m (33 ft).
