Asked by Deanna
A hydrometer consists of a spherical bulb and a cylindrical stem with a cross-sectional area of 0.400 cm^2. The total volume of the bulb and stem is 13.2 cm^3. When immersed in water, the hydrometer floats with 8.00 cm of stem above the water surface. When the hydrometer is immersed in an organic fluid, 3.20 cm of the stem is above the surface. Find the density of the organic fluid.

change in volume displaced = (8-3.2)(.4)
= 1.92 cm^3
mass in water = mass in fluid
m = (volume in fluid)(density of fluid) = (volume in water)(density of water which is 1 gm/cm^3)
density of fluid = (volume in water/volume in fluid)(1)
Volume in water = 13.2 -8*.4
Volume in fluid = 13.2- 3.2*.4
= 1.92 cm^3
mass in water = mass in fluid
m = (volume in fluid)(density of fluid) = (volume in water)(density of water which is 1 gm/cm^3)
density of fluid = (volume in water/volume in fluid)(1)
Volume in water = 13.2 -8*.4
Volume in fluid = 13.2- 3.2*.4
