Red gold is a gold-copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 7.61 g and has a volume of 0.432 cm^3? Gold has a density of 19.3 g/cm² and copper has a density of 8.96 g/cm^3.
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.

the atomic mass is the bottom number on the element.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
