2 mole S8 (8 mole sulfur/1 mole S8)(6.022 X 1023/1 mole sulfur)
= 9.6 X 1024 atoms of sulfur
---------------------------------------
Same as any atom ratio in a compound, moles of atoms over moles of the compound times Avogadro's number.
There are 16 atoms in a molecule of sulphur, which has a chemical formula of S8.
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.
To calculate the number of moles from the number of atoms, we need to divide the number of atoms by Avogadro's number (6.022 × 10^23), which gives 3.59 moles of iron atoms.
There are 9.12 moles of hydrogen atoms in 4.56 moles of NH2NH2. Each NH2NH2 molecule contains 2 hydrogen atoms.
5.66 x 10^23 atoms of xenon is equal to 0.094 moles.
How many moles of sulphur in 1.81 X 1024 atoms of sulphur ? The answer is 3. The fact that we are talking about sulphur is immaterial. A mole is just another name for a gram molecular weight. The number of atoms in a gmw (mole) is given by Avogadro's Number, which is 6 X 1023 no matter what the element.
one mole contains 6.022 x 10^23 atoms. so multiply by 32
No moles of BaCO3 are found in any amount of Li.
20 moles x 6.02x10^23 atoms/mole = 1.2x10^25 atoms
Exactly the same as the length in a length of string.
8 atoms in S8
There are 16 atoms in a molecule of sulphur, which has a chemical formula of S8.
1,638 moles contain 9,864266723766.10e23 atoms.
10 moles LiBr (6.022 X 1023/1 mole LiBr)= 6.022 X 1024 atoms of lithium bromide=========================
20 moles
This is equivalent to 1,4 moles.
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.
