I assume you mean 6.2 x 1022, but the logic is the same for other amounts anyway.
6.2 x 1022 atoms is 0.01295 moles (using Avogadro's number)
1 mole gold weights 197 grams (many periodic tables list this in the top right corner)
Therefore your gold weights 197 x 0.01295 = 2.6 g

How many atoms are in 300 grams of gold?
There are approximately 1.93 x 10^23 atoms in 300 grams of gold. This is calculated using Avogadro's number (6.022 x 10^23 atoms/mole) and the molar mass of gold (197 grams/mole).
How many atoms of gold are in 5 grams of gold?
There are approximately 7.60 x 10^21 atoms of gold in 5 grams of gold. This calculation is based on the molar mass of gold (197 g/mol) and Avogadro's number (6.022 x 10^23/mol).
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 ===================
Every drop of seawater contains approximately how many gold atoms?
Every drop of seawater contains around 0.12 billion gold atoms.
One atom of gold weighs 3.27x10-22 grams-how many atoms will there be in one Kilogram of gold-Give your answer in Scientific notation correct to 2 Significant figures?
There would be approximately 1.86 x 10^21 atoms in one kilogram of gold. This calculation is done by taking the mass of gold in a kilogram (1000 grams) and dividing by the mass of one gold atom (3.27x10^-22 grams) to find the number of atoms.

How many atoms of gold were recovered in 197kg of gold?
To calculate the number of atoms in 197 kg of gold, you would first convert the mass of gold to moles using the molar mass of gold, which is approximately 197 g/mol. Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in the moles of gold.
How many grams of gold to make 1 oz of gold?
There are approximately 31.1 grams in 1 ounce of gold.
How many atoms are in 25.1 grams in sulfur?
25,1 grams sulfur contain 4,7147765.10e23 atoms.
How many atoms does a gold coin have?
A gold coin typically contains billions of atoms, as gold is a dense metal with a high atomic number (79). The exact number of atoms in a gold coin would depend on its size and weight, but it would be in the order of 10^22 atoms.
How many atoms are in a gold ring that has a mass of 19.7 grams?
To find the number of atoms in the gold ring, you need to convert the mass of the ring to moles using the molar mass of gold (197 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of atoms in the ring. So, for a mass of 19.7 grams of gold, you would have approximately 3.0 x 10^22 atoms.
