In stoichiometric mole to mole conversions you use the ratio of the coefficients from a balanced equation in combination with information given from a problem or procedure. You use the ratios to cross multiple and divide to find the unknown quantity.
1 mole contain 6,022 140 857(74) atoms (this is the Avogadro number).
1 mole atoms = 6.022 x 1023 atoms
Multiply moles by 6.022 x 1023 atoms/mol
3.9 moles of atoms
This is equivalent to 1,4 moles.
10,0 moles of bromine atoms contain 60,22140857.1023 atoms.Attention: valid for bromine atoms !.
There are 9.33 moles of carbon in 5.62 atoms of carbon.
1,0.10e9 atoms is equivalent to 0,166.10e-14 moles.
The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / moleTo convert moles to atoms:atoms Sc = 0.638 mol Sc6.02 x 1023 atoms Sc = 3.84E+23 atoms Sc1 mol ScMultiply by atoms per mole. Moles cancel out.

44 moles of atoms
1,638 moles contain 9,864266723766.10e23 atoms.
3.9 moles of atoms
3,00 moles of Li have 18,066422571.10e23 atoms.
This is equivalent to 1,4 moles.
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
10,0 moles of bromine atoms contain 60,22140857.1023 atoms.Attention: valid for bromine atoms !.
The conversion factor you need for this problem is Avogadro's number.(6.02 x 1023 atoms germanium/1 mole germanium) = 1... OR ...(1 mole germanium/6.02 x 1023 atoms germanium) = 1Since you want to end up in units of moles of Ge, this goes in the numerator (on top). You want to convert from atoms Ge, so this goes in the denominator (on the bottom).atoms Ge1 mole Ge = moles Ge6.02E+23 atoms Ge
There are 9.33 moles of carbon in 5.62 atoms of carbon.
