Density is 2 gm/cm3 and it sinks on water bcz it has more density than water

Calculation of Density:
- Given volume of packet = 300 cm³, mass = 600g
- Density = mass/volume = 600g/300cm³ = 2g/cm³

Analysis for Floating/Sinking:
- Water density = 1g/cm³
- The density of the packet (2g/cm³) is greater than the density of water (1g/cm³)
- Based on Archimedes' principle, an object will float if its density is less than the density of the fluid it is placed in, and sink if its density is greater
- Since the density of the packet is greater than that of water, it will sink in water

Explanation:
- When an object is placed in a fluid, the upward buoyant force acting on it is equal to the weight of the fluid displaced by the object
- If the weight of the object is greater than the buoyant force, it will sink
- In this case, the weight of the packet (mass x acceleration due to gravity) is greater than the buoyant force exerted by water on it
- Therefore, the packet will sink in water due to its higher density compared to water

In conclusion, the packet with a density of 2g/cm³ will sink in water with a density of 1g/cm³ because of the principle of buoyancy and the relative densities of the packet and water.
