Every drop of seawater contains approximately how many gold atoms?
9.2 grams
What is the mass of potassium if a potassium sample contains 5 times the number of atoms as in 9.85 grams of gold?
The gram atomic mass of gold is 196.967 and that of potassium is 39.0983. Therefore, equal numbers of atoms of potassium are supplied by 39.0983/196.967 the mass of potassium compared with gold. 5 X 9.85 = 49.25. This contains the same number of gold atoms as 49.25(39.0983/196.967) or 9.78 grams of potassium contains of potassium atoms, to the justified number of significant digits (limited by the number "9.85", assuming that "5" is intended to be exact.)
You have 8 grams of gold need to know what it is in grams?
8 grams of gold i still 8 grams of gold. so its 8 grams.
How many gold atoms are there in 493 g of gold?
a mole of gold weighs 197 grams and there are just over 6E23 atoms in a mole......... that's all you need to know........ now you compute it yourself! Your answer will be correct to at least 2 digits... which is all anyone usually cares about anyway.
Is it true that there is gold in copper sheet?
A copper sheet is made of... surprise... copper. No gold.
How many atoms of gold are in 5 grams of gold?
Atomic mass of Ag: 107.9 grams5.00 grams × (6.02 × 1023 atoms) / (107.9 grams) = 2.79 × 1022 atoms Ag
How many atoms does 100 grams of gold have?
Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.
How many atoms are in 300 grams of gold?
The answer is 9,17233.1023 atoms.
5.6 moles of gold contain how many atoms?
5.0 grams gold (1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au) = 1.5 X 1022 atoms of gold ===================
How many atoms of gold were recovered in 197kg of gold?
Quite a few! 197 kilograms gold (1000 grams/1 kg)(1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au) = 6.02 X 1026 atoms of gold ------------------------------------
Every drop of seawater contains approximately how many gold atoms?
9.2 grams
What is the mass of 175 atoms of gold?
equation: g= 175 atoms x 1 mol/6.02x10^23 x 196.97g/1 mol ---> 175 atoms of gold weigh 5.73x10^-20 grams.
If you weigh a piece of gold for example how could you figure out the exact number of atoms in that sample?
Sticking with gold : Gold has an atomic weight of 196.9665 so 196.9665 grams of gold has Avogadro's number of atoms : 6.02 x 10 to the 23 atoms. Use proportions to figure for other weights.
How many grams of gold are there in 15.3 moles of Au?
If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.
How many atoms of gold are in a necklace that weighs 12.7g?
12.7 g gold (1 mole Au/197.0 grams)(6.022 X 10^23/1 mole Au) = 3.88 X 10^22 atoms of gold
How many atoms are in a gold ring that has a mass of 19.7 grams?
Well, firstly you need to know if it is pure gold. Assuming that it is, convert the grams to moles 19.7g Au x 1molAu/197.0gAu = 0.1moles Au And then, to get the number of atoms in 0.1 moles of gold, multiply it by Avogadro's number, 6.22x10^23 atoms per mole 0.1mol Au x 6.22x10^23atoms/mole = 6.22x10^22
Estimate the number of gold atoms in a gold coin with a diameter of 1 cm and a thickness of 1mm?
A gold coin with a diameter of 1 centimeter and a 1 mm thickness has a volume of .07854 cubic centimeters. Gold has a density of 19.30 grams per cubic centimeter. There is 1.5158 grams of gold or 7.7 millimoles or 4.637 E21 atoms.
