a graduated cyclinder contains 20.0 ml of water. An irregular shaped object is placed in the cyclinder and the water rises to 31.2 ml mark. if the object has a mass of 54.8 g what is the density?

First, write down your knowns:
-grad cylinder has 20.0mL of H20
-level rises to 31.2mL mark after adding object
-object's mass = 54.8g
-Density = Mass/Volume
Next, determine what the question is asking:
-What is the object's density?
Finally, use your "knowns" to answer the question:
Density = 54.8g / (31.2mL - 20.0mL)
= 4.8928571 g/mL
= 4.89 g/mL

The amusing thing about you asking the question that any really stupid chemistry student could answer is how much time it took you to type in the question, which surely was far more time than it would take for you to solve the problem yourself, assuming you listened to your teacher or read the book, both of which it is clear you have not done.
If you have to aske such a simple question as this, what do you think you are going to do when you get to the difficult problems?
Yes, that's right, you are going to flunk!

About as dense as your head for asking.

54.8/(31.2-20)= 4.89g/mL.

4.89 g/ml
54.8/(31.2-20)
