Each one consists of a spherical bulb attached to a cylindrical tube. One of them is placed into a vat of water, and the other is placed into a vat of alcohol. Both hydrometers are floating upright. }1cm The cross-sectional area of the stem is 0.4 cm2. The total volume {cylinder + bulb] of the hydrometer is 15 cm3. When the hydrometer is placed in water, 8 cm of the stem is above the water. When the hydrometer is placed in alcohol, only 1 cm of the stem is above the liquid. What is the density of the alcohol? {Take the density of water to be 1 g/cm3). Give your answer in units of g/cm3
