You are measuring the density of an irregularly shaped solid. Direct weighing gives a mass of 31.2789 grams. After placing the object in a graduated cylinder, the volume reading increased from 14.2 mL to 25.9 mL. What is the density of the object

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being
