Question

the volume of 50 gram of substance is 20 CM if the density of water is 1 gram CM will the substance sink or float

Answer 1

The volume of 50 g of a substance is 20 cm3. If the density of water is 1 gcm3, will the
substance float or sink?

Mass of substance (m) = 50 g

Volume of substance (V) = 20 cm^3

Density of substance (D) = m/v = 50g/20cm^3 = 2.5gcm^-3

The substance will sink in water, as its density (2.5 gcm^-3) is more than the density of water
(1 gcm^-3)

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______❤
