Two identical hydrometers are shown in the figure below. Each one

Two identical hydrometers are shown in the figure below. 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. The cross-sectional area of the stem is 0.6 cm2. The total volume (cylinder + bulb) of the hydrometer is 14 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/cmg) g/cm3
