An object of mass 50 g has a volume of `20 cm^(3)`
Calculate the density of the object. If the density of water `1//g cm^(2)`, state whether the object will float or sink in water.

Explanation

We know that: Destiy `=("Mass of the object" )/("volume of the object")`
Here Mass of the object =50 g
And volum of the object = `20=cm ^(3)`
Now putting these values of mass of and volume of the object in the above formula ,we get : Density of object `=(50 g)/(20 cm)^(3)`
`=2.5 g//cm^(3)`
Thus the density of object is `2.5 g//cm^(3)`
Since the density of object `(2.5 g// cm ^(3))` is greater than the density of water `(1 g // cm^(3))` therefore , the object will sink in water.
