Question

an object has a mass of 10g when weighed in air. The same object has a mass of 2g when weighed in water. what percent of the object is submerged and what is the density?

Answer 1

Let the density of the object is .

Weight loss of the object in water is

Let the water displaced by the object is V.

  

  

The volume of the object is 8 mL.

The mass of the object m=10 g.

The density of the object

  

  

The density of the object is 1.25 g/mL.

Now the density of the object (1.25 g/mL) is greater than the water (1 g/mL).So the object submerged fully into water.

a)   100% of the object submerged in the water.

b) The density of the object is 1.25 g/mL.
