At one point in time, the price of gold was about $1400 per ounce, while that of silver was about $20 an ounce. The "ounce" in this case is the troy ounce, which is equal to 31.1035 gg. (The more familiar avoirdupois ounce is equal to 28.35 g.) The density of gold is 19.3 g/cm3g/cm3 and that of silver is 10.5 g/cm3.
If you found a spherical gold nugget worth $3.00 million, what would be its diameter?
How much would a silver nugget of that size be worth?
Red gold is a gold‑copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 8.85 g8.85 g and has a volume of 0.545 cm30.545 cm3. Gold has a density of 19.3 g/cm319.3 g/cm3 and copper has a density of 8.96 g/cm38.96 g/cm3. Calculate the percentage by mass of each metal in the jewelry.

- 1f a piece of hard, white blackboard chalk is heated strongly in a flame, the mass of the piece of chalk will decrease, and eventually the chalk will crumble into a white dust. Does this change suggest that the chalk is composed of an element or a compound?arrow_forwardOn October 21, 1982, the Bureau of the Mint changed the composition of pennies (see Exercise 120). Instead of an alloy of 95% Cu and 5% Zn by mass, a core of 99.2% Zn and 0.8% Cu with a thin shell of copper was adopted. The overall composition of the new penny was 97.6% Zn and 2.4% Cu by mass. Does this account for the difference in mass among die pennies in Exercise 120? Assume the volume of the individual metals that make up each penny can be added together to give the overall volume of the penny, and assume each penny is the same size. (Density of Cu = 8.96 g/cm3; density of Zn = 7.14 g/cm3).arrow_forwardGold leaf, which is used for many decorative purposes, is made by hammering pure gold into very thin sheets.

(b) What will the bottle look like when you take it out of the freezer?arrow_forwardPotassium sulfate has a solubility of 15 g/ 100 g water at 40C. A solution is prepared by adding 39.0 g of potassium sulfate to 225 g of water, carefully heating the solution, and cooling it to 40C. A homogeneous solution is obtained.
