Density is the ratio of a sample's mass to its volume. A bar of lead has a mass of 115.2 g. When it is submerged in 25.0 mL of water in a graduated cylinder, the water level rises to 35.5 mL. What is the density of the lead

Explanation:

Given :

Mass of a bar of lead = 115.2 g

Initial water level = 25 mL

Final water level = 35.5 mL

Difference in the water level = 35.5 - 25

                                               = 10.5 mL

                                               =

We know that when a body is submerged in water, it displaces its own volume of water.

Therefore, the volume of the lead bar = volume of the water displaced = 10.5 mL  =

We know that mathematically, density is the ratio of mass of body to its volume.

Density of the lead bar is given by :

  =

the answer is c i believe

it's all four options.
