Question

the volume of 50 gm of substance is 20 cm^ 3 will the subtance float or sink

Answer 1

mass = 50g

volume = 20cm³

density = mass/volume = 50/20 = 2.5 g/cm³

density of water = 1 g/cm³

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

The volume of water displaced = 20 cm³

mass of water displaced = volume×density = 20×1 = 20g

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 sub. , M= 50 g

Volume of sub., V= 20 cm^3

density of the substance

= M/V

=50/ 20

= 2.5 g/cm^3

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

I hope, this will help you.☺

Thank you______❤
