The density of an object is 1.23 g/cm3. In which of the following materials will it float?

water (density = 1.00 g/c m3)
olive oil (density = 0.920 g/c m3)
ethyl alcohol (density = 0.789 g/c m3)
citric acid (density = 1.660 g/c m3)

Respuesta :

in order to float the demsoty of the floating obkect must be lower then the liquid it is in. the only one that works for is Citric acid

Answer: The correct option is Citric acid which has a density of [tex]1.660 g/cm^3[/tex]

Explanation: Density plays an important role to determine whether a substance will float or sink.

A substance will float when its density is less than the density of liquid in which it is placed.

And the substance will sink, if it is placed in the liquid having less density than its own.

Density of object = [tex]1.23g/cm^3[/tex]

And we are asked in which liquid will it float, hence the liquid having higher density than the object will make the object float.

Hence, the correct option is Citric acid having density [tex]1.660g/cm^3[/tex]
