It is given that the volume of a 500 g packet is 350 cm3. What do you think, the packet will float or sink in water if the given density of water is 1 gcm-3 ?
Given :
Volume of packet = 350 cm 3
Weight of the packet = 500 g
Density of water = 1 gcm -3
To find : Density of packet, in order to compare it with density of water and see whether the packet will float or sink
Density of packet = Weight of packetVolume of packet
= 500g350cm 3
= 1.428 gcm -3
Therefore, the packet will sink because the density of the packet is greater than the density of water.
