69. The density of liquid gallium at 30^° C is 6.095 g/ml. Because of its wide liquid range (30 to 2400^° C) , gallium is used as barometer fluid at high temperature. What height (in cm) of gallium will be observed on a day when the mercury barometer reads 740 torr? (The density of mercury is 13.6g/ml).
