Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.

lactometers which are used to determine the purity of a sample of milk and hydrometer used for determining density of liquids are based on this principal...
mass -50g
volume- 20cm^3
density =50g/ 20cm^3=5g/2cm^3=2.5g/cm^3
as density of the object is greater than density of water ....thus it will sink...
hope it helped uuh...
_/\_Hello mate__here is your answer--
_______________________
⭐ CONCEPT:-- If the density of an object is more than the density of a liquid, then it sinks in the liquid. On the other hand, if the density of an object is less than the density of a liquid, then it floats on the surface of the liquid.
________________________
Mass of sub. , M= 50 g
Volume of sub., V= 20 cm^3
density of the substance
= M/V
=50/ 20
= 2.5 g/cm^3
The density of the substance is more than the density of water (1 g cm^−3). Hence, the substance will sink in water.
I hope, this will help you.☺
Thank you______❤
