2. The volume of a 500 g sealed packet is 350 cm. Will the packet
float or sink in water if the density of water is 1 g cm-3? What
will be the mass of the water displaced by this packet?

_/\_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 = 500g
Volume = 350cm^3
Density = Mass/Volume
= 500/350
= 1.42g/cm^3
The packet will sink because density of the packet is greater than the density of water.
Mass of water displaced by packet
= 350cm^3 X 1g/cm^3
= 350g
________________________
Mass of packet, M = 500 g
Volume of packet,V = 350g/cm^3
Dencity of sealed packet =M/V
= 500 /350
= 1.428 g/cm^3
The density of the substance is more than the density of water (1 g/cm3). Hence, it will sink in water.
The mass of water displaced by the packet is equal to the volume of the packet, i.e., 350 g.
I hope, this will help you.☺
