5.0 grams gold (1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au)
= 1.5 X 1022 atoms of gold
===================
To find the number of atoms in 100 grams of gold, you would first calculate the number of moles using the molar mass of gold (197 grams/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, approximately 3.01 x 10^23 atoms of gold are present in 100 grams.
To find the number of moles of PCl3, you need to first calculate the number of moles of Cl atoms in 3.68 * 10^25 atoms. There are 3 Cl atoms in each molecule of PCl3, so you divide the number of Cl atoms by 3 to get the number of moles of PCl3.
To find the number of atoms in 0.39 moles of Ga (gallium), you first need to calculate the number of moles in 0.39 moles of Ga. Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms. So, for Ga, there would be approximately 2.35 x 10^23 atoms in 0.39 moles of Ga.
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
6. 1 mole of CS2 contains 1 mole of carbon and 2 of sulfur.
12,4439 kg of gold contain 63,177 moles.
1,638 moles contain 9,864266723766.10e23 atoms.
2,50 moles of silicon contain 15,055352142.10e23 atoms.
5,26 moles of oxygen contain 31,676.10e23 atoms.
Two moles of neon contain 12,044281714.10e23 atoms.
2,89 moles of aluminium contain 17,40398707673.1023 atoms.
10,0 moles of bromine atoms contain 60,22140857.1023 atoms.Attention: valid for bromine atoms !.
8,23.1023 atoms Mg is equivalent to 1,366 moles.
1,46 moles of aluminum fluoride contain 35,16848.10e23 atoms.
The answer is 0,0625 mol.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
