Suppose you have two 100-mL graduated cylinders. In each cylinder there is 44.0 mL of water. You also have two cubes: one is lead (density = 11.3 g/mL), and the other
is aluminum (density = 2.70 g/mL). Each cube measures 1.9 cm on each side.
Part A
After you carefully lower each cube into the water of its own cylinder, what will the new water level be in each of the cylinders?

Red gold is a gold-copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 8.50 g and has a volume of
0.535 cm. Gold has a density of 19.3 g/cm² and copper has a density of 8.96 g/cm'. Calculate the percentage by mass of each
metal in the jewelry. Assume the total volume of the jewelry is the sum of the volumes of the two metals it contains.
gold:
copper.
Pure gold is defined as having 24 carats. When mixed in an alloy, the carats of gold are given as a percentage of this value. For
example, a piece of jewelry made with 50% gold has 12 carats. State the purity of this piece of red gold jewelry in carats.
purity:
carats
