Question

volume of a 500g sealed packet is 350 cm3. will the packet float or sink in the water if the density of water is 1g/cm-3? what will be the mass of the water displaced by this place

Answer 1

Density = mass / volume
Density of packet = 500 / 350
= 1.42 g/cm3
hence, as we know that if a body have higher density than the density of substance in which the body is going to immerse then the body will sink.
in this case density of packet is more than the density of water so, packet will sink

Answer 2

Here mass of packet, M = 500g

Volume of the packet, V = 350cm3

Density of packet, d = m/v = 500g/350cm3 = 1.428g/cm3

Since the density of packet is more than the density of solution, packet will sink

Mass of water displaced = volume of packet* density of solution

= 350 × 1.2

= 420 g
