This document is a student laboratory report that details using an aerometer or hydrometer to determine the density of various liquids. It includes an introduction to the theory behind how aerometers measure density, the experimental procedure, a table of density readings for oil, water, and a saltwater solution, and a brief discussion section. The aim was to use appropriately calibrated aerometers to ascertain properties like alcohol content, fat content, concentration, and antifreeze content by measuring density.

3. Aim of experiment:
Determining the liquid density

4. Introductions of theory:
To measure the density of liquidan aerometer is used >. It compreses
an enclosed glass bulb which is filled with lead shot at the bottom ans
above that with air
The handlingis quite sample L the aerometer is placed in the liquidand
because of the lead filling it alwaysrights it self vertically . the
aerometer sinks more or less deeply into the liquiddependingon the
thikness .
Since the aerometer is suspended its lifting force must be exactly the
same as its force due to weight i.e its apparent weight is equalto zero :
FG,liquid= FG-FA=0
The liquiddensity can be read directly from the scale
Two differently calibrate aerometers are supplied:
Measure range
𝜌 = 0.8 − 1.0
𝑔
𝑐𝑚3
liquids lighter than water e.g alcohol or petroleum
𝜌 = 0.8 − 1.0
𝑔
𝑐𝑚3
liquids heavier than glycerin or a salt solution

5. Procedure :
Because solutes chang the density of a solution appropriately
calibrate aerometers can be used among other application to as
certain the alcohol content of drinks the fat content of milk the
concentraition of battery acid and the antifreeze content in
motor vehicle coolant

6. Table of reading :
no liquid Density( 𝜌) kg/m3
1 oil 0.868
2 Water 0.998
3 Water + salt 1.068

7. Discussion :
2-They put this lead or mercury to cause the instrument to
float upright in a liquid
