You have been mining for gold and you have found a nugget and are about to be rich. the density of the gold is 19.3 grams/cubic centimeter or g/cc. your sample has a mass of 972 grams and is nearly a perfect cube, each side measuring 3 cm. find the the density of your sample (hint: you must find the volume of the cube first). after you've done this compare the given density of gold to your calculated value. is your sample pure gold? explain.
