Which instrument is used to measure the density of milk?
Lactometer
Lactometer is a hydrometer instrument that is used to check for the purity of milk by measuring milk’s density; usually it works on the principle of gravity of milk.
What instrument can be used to measure relative density?
hydrometer
hydrometer, device for measuring some characteristics of a liquid, such as its density (weight per unit volume) or specific gravity (weight per unit volume compared with water).
How do you calculate the relative density of oil?
ρ=m/V where ρ=density, m=mass and V=volume. The density of most oils will range between 700 and 950 kilograms per cubic meter (kg/m3). By definition, water has a density of 1,000 kg/m3.
How do you find the relative density of milk groundnut oil and kerosene?
The relative density of kerosene is 0.8g/cm. The relative density of groundnut oil is 0.93g/cm. Relative density is also known as specific gravity.
How do you find the relative density of milk?
Lactometer is used for measuring the density (creaminess) of milk. It is essentially a hydrometer which is an instrument used to measure the specific gravity (or relative density) of liquids; that is, the ratio of the density of the liquid to the density of water.
Which instruments is used to measure milk?
The device used for measuring the quality of milk is a lactometer. It is an instrument that measures the amount of water added and the volume of cream in the sample of milk.
Which instrument is used to test the purity of milk?
Lactometers
Lactometers are used for milk purity checker and also a very reliable instrument.

What is the relative density of milk?
“Milk has a weight density of 64.2 to 64.6….Density of Milk.
NAME | LBS/FT3 DENSITY | SPG |
---|---|---|
Milk | 64.4 | 1.035 |
Which is denser rubber or plastic which is denser wood or cork?
Rubber is denser than plastic.
How to determine the density of milk?
6.4 Methods for the Determination of the Density and Specific Gravity of Milk A very common instrument for direct measurement of density of a liquid is the hydrometer, which measures the volume displaced by an object of known mass.
What instrument is used to measure the density of a liquid?
A common laboratory device for measuring fluid density is a pycnometer; a related device for measuring the absolute density of a solid is a glass pycnometer. Another instrument used to determine the density of a liquid or a gas is the digital density meter – based on the oscillating U-tube principle.
Does specific gravity of milk give a conclusive indication of composition?
The specific gravity of milk does not give a conclusive indication of its composition since milk contains a variety of substances that are either heavier or lighter than standard substance i.e. water. Additional tests for fat content are necessary to determine overall composition of milk.
What is the percentage of water in milk?
Most milk is composed of 80 to 90 percent water. The remaining 10 percent consists of the major nutrients needed by the body for good health, including fats, carbohydrates, proteins, minerals, and vitamins. Cow milk contains approximately 87\% of water, 3 to 4\% protein, 4 to 4.5\% fat, and approximately 4.5\% milk sugar (lactose).
