Answer 1

Answer:

Given:-

• 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 18 cm ? What will be the mass of the water displaced by this packet?

Solution:-

$\sf\red{density \: of \: packet \: = \frac{mass \: of \: packet}{volume \: of \: packet} }$

$\huge\sf\red{ = \frac{500}{300} }$

$\sf\red{ = 1.428 {cm}^{3} }$

And, density of water = 1cm³

•°•The packet will sink in water..

Mass of water displaced by packet = Volume of the packet

$\huge\sf\red{ = 350g}$

•°•Mass of water displaced is 350 g.

hope it helps

Answer 2

Answer

$density \: of \: packet = \: \frac{mass \: of \: packet}{volume \: of \: packet}$

$= \frac{500}{300} \\ { = 1.428 {cm}^{3} }$

And, density of water = 1cm³

∴The packet will sink in water.

Mass of water displaced by packet = Volume of the packet

= 350 Gram.

∴ Mass of the water displaced by this packet =350g
