1) You have a piece of gold
jewelry weighing 9.35 g. Its
volume is 0.654 cm3. Assume
that the metal is an alloy (mixture) of gold and silver, which have
densities of 19.3 g/cm3 and 10.5 g/cm3, respectively.
Also assume that there is no change in volume when the pure metals
are mixed. Calculate the
percentage of gold by mass in the alloy.
The relative amount of gold in alloy is measured in karats.
Pure gold is 24 karats; an alloy of 50% gold is 12 karats.
State the proportion of gold in the jewelry as karats.
ahw 2) A sample of an ethanol-water solution has a volume of 54.2 cm3 and a mass of 49.6 g. What is the percentage of ethanol by mass in the solution? (Assume that there is no change in volume when the pure compounds are mixed.) The density of ethanol is 0.789 g/cm3 and that of water is 0.998 g/cm3.) Alcoholic beverages are rated in proof, which is a measure of the relative amount of ethanol in a beverage. Pure ethanol is exactly 200 proof; a solution that is 50% ethanol by volume (not mass) is exactly 100 proof. What is the proof of the given ethanol-water solution?
