Question

The volume of a 500 g sealed packet is 350 cm3. 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?​

Answer 1

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

Answer 2

Given,

Volume=350 cm^3

Mass=500 g

Therefore,

Density=Mass÷Volume=500÷350 =10/7=1.42 g/cm^3

Since the density of the packet is greater than density of water, it will sink.

Again,

Density of water=1 g/cm^3

Volume of water=350 cm^3

Mass of water displaced=?

We know,

Density=Mass÷Volume

=>Mass=Density×Volume=1×350=350 g

HOPE IT HELPS

Thanking you
