5. Gold is the most malleable metal known. It can be pressed or beaten into very thin sheets called gold leaf. The diameter of a gold atom is 0.29 nm. (1 nm is equal to one billionth of a meter, or in mathematical terms 1,000,000,000 nm = 1 m) Assuming the atoms are stacked one on top of the other, calculate the number of atoms of gold that make up the thickness of a 0.000005 inch gold leaf. (1 pt) First, you should consider drawing a picture of the situation and labeling all you can. Then, you may want to calculate the thickness of the gold leaf in terms of nm so that the lengths are in the same units. Remember that 1 inch = 2.54 cm. Show your work. 6. If the mass of one gold atom in grams is 3.271 x 10-22 grams, and one ounce of gold is equal to 28.3 grams, how many atoms are in one ounce of gold? Next, take the number of atoms you just got and divide by the number of atoms in one mole we listed in the introduction. What is the number of moles of gold atoms in one ounce of gold? (1 pt) 5.
