a) a sphere of gold with a radius of 12.1 cm. (The volume of a sphere with a radius r is V = (4/3) π r3; the density of gold is 19.3 g/cm3.) -answer in scientific notation (b) a cube of platinum of edge length 0.024 mm (density = 21.4 g/cm3).- answer in scientific notation (c) 66.9 mL of ethanol (density = 0.798 g/mL).- answer in scientific notation
Indiana Jones is in a temple searching for artifacts. He finds a gold sphere with a radius of 2 cm sitting on a pressure sensitive plate. To avoid triggering the pressure plate, he must replace the gold with something of equal mass. The density of gold is 19.3 -103 kg/m3, and the volume of a sphere is V = 4/3 Ar3. Indy has a bag of sand with a density of 1,602 kg/m3. (A) What volume of sand must he...
The density of gold is 19.3 g/cm3. What volume (cm3) would be occupied by a piece of gold with a mass of 103.5 g?
Red gold is a gold‑copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 8.35 g and has a volume of 0.581 cm3. Gold has a density of 19.3 g/cm3 and copper has a density of 8.96 g/cm3. Calculate the percentage by mass of each metal in the jewelry. Assume the total volume of the jewelry is the sum of the volumes of the two metals it contains. gold: % : copper: % : Pure...
Red gold is a gold‑copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 8.80 g and has a volume of 0.594 cm3. Gold has a density of 19.3 g/cm3 and copper has a density of 8.96 g/cm3 . Calculate the percentage by mass of each metal in the jewelry. Assume the total volume of the jewelry is the sum of the volumes of the two metals it contains. gold: % copper: % Pure gold...
A solid metal sphere has a radius of 3.83 cm and a mass of 1.624 kg . What is the density of the metal in g/cm3? (The volume of sphere is V=43πr3.)
Suppose you measured the mass and volume of a piece of material you think is gold. You calculate the density to be 18.6 ± 4 g/cm3. The accepted density of gold is 19.3 g/cm3. Calculate the percent error in your measurement. (You are allowed to keep 2 digits in the answer).
A solid metal sphere has a radius of 3.39 cm c m and a mass of 1.877 kg k g . What is the density of the metal in g/cm3 g / c m 3 ? (The volume of sphere is V=43πr3 V = 4 3 π r 3 .)
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 g. (The more familiar avoirdupois ounce is equal to 28.35 g.) The density of gold is 19.3 g/cm3 and that of silver is 10.5 g/cm3. 1. If you found a spherical gold nugget worth $3 million, what would be its diameter? 2. How...
