Question

The volume of 500g sealed packet is 350 cm3. What is the density of the packed packet? Will it float or sink in water, if it has the density of 1g/cm3. What will be the mass of water displaced by this packet???

Answer 1

Answer:



The density of the substance is more than the density of water (1 g cm-3). Hence, it will sink in water.

As the packet is fully submerged in water,

Mass of water displaced by the packet = volume of the packet x density of water

                                                    = 350 cm3 × 1 g/cm3 = 350 g

Concept Note - Density of an object is a key factor in deciding whether the object will sink or float.

Answer 2

_/\_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 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.☺

Thank you______❤
