In the PreLab Assignment you determined the density of 10 pennies using Archimedes' water displacement approach.  If the 10 pennies weigh 28.676 g and the initial volume in the graduated cylinder is 24.9 mL and the final volume in the graduated cylinder + 10 pennies is 28.5 mL, what is the . . . .    a. average mass (g) of a single penny?

A piece of a metal alloy with a mass of 114 g was placed into a graduated cylinder that contained 25.0 mL of water, raising the water level to 42.5 mL. What is the density of the metal?0.154 g/cm30.592 g/cm32.68 g/cm36.51 g/cm37.25 g/cm3

A rock has a mass of 850g and was placed in a graduated cylinder with an initial volume of 35ml, which changed into 50ml. Calculate the density of the rock

average density (g/mL) of a single penny?

An object has a mass of 20 g and displaces a volume of 5 mL. What is the object's density?

Use the worked example above to help you solve this problem. A bargain hunter purchases a "gold" crown at a flea market. After she gets home, she hangs it on a scale and finds its weight to be 7.99 N (Figure (a)). She then weighs the crown while it is immersed in water, as shown in Figure (b), and now the scale reads 7.00 N.What is the density of the crown? kg/m3Is the crown made of pure solid gold?YesNo
