Gold Price Conversion
Another issue of conversion?
In 1933, the United States abandoned the gold standard internationally, and the price of gold rose $ 20.00 to $ 35.00/troy oz. The gold coin of twenty dollars, known as the double eagle, weighs 33,436 grams of gold and was 90.0% by mass. (A) What was the value Golden Eagle before and after the price change? (B) How many coins could make 2.00in3 gold (1 troy ounce .= 31.1 g, d = 19.3g/cm3 gold)?
The value of gold is its mass multiplied by the price. We know the mass of the coin, but only 90% of it was gold: the mass of gold in the currency = (33.436g * 0.9) = 30.0924g now also have to convert this to mass troy ounces. (31.1 g / oz) = in the gold coin 30.0924g = 0.967601 troy oz. / Now we can find the value of that gold, long before the price change: Price = 0.967601 troy oz. * $ 20.00/troy oz = $ 19.35202 rounding to three significant figures: $ 19.40 This is what the dollar and twenty pieces of gold was worth before the price change. $ 19.40. Strange, no? Anyway, after the price change, the U.S. and was not the gold standard. A coin worth now what it said was worth, rather than the quantity of gold on the inside was worth it. So a gold coin of twenty U.S. dollars worth …. exactly twenty dollars. Always and forever. This is a trick question, your classmates will figure the value of gold after Price change, but that's not what the question refers to:. For the part b is necessary to find out how many cubic centimeters is 2.00 cubic centimeters: A = 2.54 cm a ^ 2 = 6.4516 cm ^ 2 ^ 1 3 = 16.387064 cm ^ 3 2 ^ 3 = 32.774128 cm ^ 3 The density of gold is 19.3g/cm ^ 3. Multiply by the previous value, we have: 19.3g/cm ^ 3 * ^ 3 = 32.774128 cm 632.5406704g. There are about 632.5 grams in 2 cubic inches of gold. We know from part a) that an eagle of gold 30.0924g two uses. How many Sometimes we cut gold 30.0924g 632.5406704g block? 632.5406704g / 30.0924g = 21.0199476 ~ What little remains is probably due to rounding errors, so the answer is of 21 coins.
