Concept explainers
Gold, one of the most sought-after metals in the world, has a density Of 19.3 g/cm3, a melting point of 1064 °C, and a specific heat of 0.129 J/g °C. A gold nugget found in Alaska 1998 weighed 20.17 1b. (2.4, 2.6, 2.7, 3.3, 3.5)
Gold nuggets, also called native gold, can be found in streams and mines.
a. How many significant figures are in the measurement of the weight of the nugget?
b. Which is the mass of the nugget in kilograms?
c. If the nugget were pure gold, what would its volume be in cubic centimeters?
d. What is the melting point of gold in degrees Fahrenheit and kelvins?
e. HOW many kilocalories are required to raise the temperature of the nugget from 500. °C to 1064 °C?
f. If the price of gold is $42.06 per gram, what is the nugget worth in dollars?
