12,4439 kg of gold contain 63,177 moles.
6.1010 g of gold is equivalent to 3,046.108 moles.
19,55 moles of gold is equal to 3 850,7 g.
Let's see. 3 moles gold (197.0 grams/1 mole Au) = 591 grams of gold ----------------------------- 10 mole iron (55.85 grams/1 mole Fe) = 558.5 grams of iron ----------------------------- So, 3 moles of gold has more mass that 10 moles of iron. (heavier)
18K means 18 karats. Karats are how gold is measure. The number 18 means that the piece is 75% gold and 25% alloy. HGE is the logo of the company who made the piece. Not true! HGE stands for HEAVY GOLD ELECTROPLATE, which means the ring is PLATED with 18k gold and has no buyer value.
Uhh.. about 3fiddy
100kg = 3,527.4oz or 3,215.07 troy ounces.
2.8 moles of gold would be 550g of gold. Multiplying the amount of moles by the molar mass (197.0 grams/moles) will give you the grams by cancelling out the moles units.
As of January 3, 2014, 100 kg of gold would be worth $3,978,976.
12,4439 kg of gold contain 63,177 moles.
6.1010 g of gold is equivalent to 3,046.108 moles.
1 g of gold is equal to 0,006 moles.
19,55 moles of gold is equal to 3 850,7 g.
Let's see. 3 moles gold (197.0 grams/1 mole Au) = 591 grams of gold ----------------------------- 10 mole iron (55.85 grams/1 mole Fe) = 558.5 grams of iron ----------------------------- So, 3 moles of gold has more mass that 10 moles of iron. (heavier)
Using avagadro's number of 6.022 x 10 to the 23rd atoms/mole. The answer is 1.99 moles of gold
Determining how heavy it is, and thus it's value.
