11 When an object is dropped into a graduated cylinder, the water in the
cylinder rises from 50.OmL to 56.3 mL. The mass of the object is 15.9 g.
What is the density of the object? *

Explanation:

The density of a substance can be found by using the formula

From the question

mass of object = 15.9 g

volume = final volume of water - initial volume of water

volume = 56.3 - 50 = 6.3 mL

It's density is

We have the final answer as

Hope this helps you

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.
