Question

The volume of 50g of a substance is 20cm3. If the desity of water is 1g cm-3 , will the substace float or sink

Answer 1

volume of substance -20cm3
mass of substance. -50g
density of water -1gcm-3 .
density -mass /volume
50/20 =2.5 gcm3.
the substance will be sink. ..because the density of substance is greater than water density. .

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______❤
