본문내용
2. (5 points) Gold is alloyed (mixed) with other metals to increase its hardness in making jewelry. Consider a
piece of gold jewelry that weighs 0.3418 oz and has a volume of 0.675 cm3. The jewelry contains only gold
and silver, which have densities of 19.3 g/cm3 and 10.5 g/cm3, respectively. If the total volume of the jewelry
is the sum of the volumes of the gold and silver that it contains, calculate the percentage of gold (by mass) in
the jewelry, using the correct number of significant figures in your answer (1 oz = 28 g).
3. (3 points × 2 = 6 points) How did Rutherford interpret the following observations made during his scattering
experiments? (a) Most particles were not appreciably deflected as they passed through the gold foil. (b) A
few particles were deflected at very large angles.
