A gold nugget found in Ruby, Alaska in 1998 weighs 293.90troyounces . if 1 troyounce is 31.1035 g, what is the mass of the nugget in grams? Express your answer to five significant figures and include the appropriate units.

Explanation / Answer

I used an on-line converter to convert troy ounces to grams:

294.10 troy ounces = 9147.5 grams

V = m/d = 9147.5/19.3 g/cm^3 = 474 cm^3

thickness = 0.0035 in X 2.54 cm/in = 8.9 X 10^-3 cm

area of foil = 474 cm^3 / 8.9 X 10^-3 cm = 5.33 X 10^4 cm^2 = 5.33 m^2
