If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.
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
Approx 3.32*10^23 atoms.
4.2 X 10^24 atoms of gold / 6.022 X 10^23 atoms per mol) = 7.0 moles of gold
6.02*10(to the 23rd)
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.
If 3,6 x 10-5 is grams the number of atoms is 1,1.10e17.
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
2.936*10^24 atoms....
There are 0.0156 Troy ounces of pure gold in the US $10 gold or 15.0463 grams.
7,5.1021 uranium atoms = 2,9644 grams
Approx 3.32*10^23 atoms.
Approx 1.5*10^23 atoms.
Yes. One mole (6.02 x 10 to the 23 atoms) would weigh 197 grams.
