Answer:
Density of sealed packet = 500/350 = 1.42 g/cm3
The density of the sealed packet is greater than the density of the water
Therefore the packet will sink.
Considering Archimedes Principle,
Displaced water volume = Force exerted on the sealed packet.
Volume of water displaced = 350cm3
Therefore displaced water mass = ρ x V
= 1 × 350
Mass of displaced water = 350g.
