Question

How is the density of a liquid measured with the help of a density bottle?

Answer 1

Hint:The above problem can be resolved by considering the flask of known volume and taking the measurement of the weight contained by the flask at various conditions. Once the weight of the flask is obtained, then the formula for the density of liquid could be applied to obtain the desired result.

Complete step by step answer:
The density bottles are the special laboratory equipment used to measure any specific liquid's density with moderate viscosity. Moreover, they are not categorized as the volumetric instruments, but they have calibrated the volumetric flasks likewise.
To determine the density of any given liquid, the steps followed is given as,
1. Firstly, take a bottle of known volume (V) and determine the weight of the density bottle, when it is empty. Say the weight is \[{W_1}\].
2.Then the empty bottle is filled with the desired liquid whose density is to be calculated.
3. Now, measure the weight of the bottle with liquid contained inside the bottle. Say the reading comes out to be \[{W_2}\] .
4. The net weight of the liquid s given as,
\[{W_{net}} = {W_2} - {W_1}\]
5. Now, apply the formula for the density to calculate the desired result for the liquid.
\[\rho = \dfrac{{{W_{net}}}}{V}\]
Here, \[\rho \] is the required density of the liquid.

Note:In order to resolve the given problem, try to understand the fundamentals of the density bottle along with its applications as well as significance. Moreover, the variety of liquids that can be employed to measure the density is to be undertaken and analyzed. Along with these, the general mathematical relation to obtaining the correct value of density is to be remembered.
