Solution

Measuring the density of a liquid with unknown mass and volume:
Take an empty and dry beaker and measure its mass using a beam balance or an electronic balance.
⇓
Let the mass of the beaker be $M_{1} g r a m$ .
⇓
Now take a measuring cylinder and pour the liquid into it and note the reading as volume (V).
⇓
Pour the liquid into the same beaker and again measure its mass using the same balance.
⇓
The balance now gives the total mass i.e., the mass of the beaker and mass of the liquid inside. Let's note this total mass as $M_{2} g r a m$ .
⇓
Mass of the liquid $M$ is given as difference between total mass and mass of the beaker.
$M = (M_{2} - M_{1}) g r a m$
⇓
Now density of the liquid is calculated by $D e n s i t y (ρ) = \frac{M a s s o f t h e l i q u i d}{V o l u m e o f t h e l i q u i d} ρ = \frac{(M_{2} - M_{1})}{V}$
Hence, density of liquid can be measured with unknown mass and volume
