15.8 moles Cu x 6.02x10^23 atoms/mole = 9.51x10^22 atoms. There are no molecules in the element Cu (copper). Molecules are found when there are two or more atoms bound together, such as in H2 gas or H2O, etc.
One mole is 2.06x10 to the 23 atoms. Therefore if there is 1.48x10 to the 25 cu atoms, we would have to divide the two values to obtain the moles of the present cu atoms. So 1.48x10 to the 25 divided by 2.06x10 to the 23 would result in 24.6 moles of cu.
Divide by Avagadro Constant. There are 24.57 moles
4.7 X 1024 atoms Cu (1 mole Cu/6.022 X 1023)
= 7.8 moles copper
------------------------
The number of atoms in 15,8 moles of copper is 95,15.10e23.
The answer is 24,576 moles copper.
The answer is 24,57 moles.
24.6
The answer is 0,465 moles.
2.01x10^22 atoms x 1 mole/6.02x10^23 atoms = 0.0334 moles
10.08 moles (there are six carbon atoms per molecule of C6H6, hence, six times the number of moles of carbon can be produced).
1 mole Kr = 6.022 x 1023 atoms 1.7 x 1025 Kr atoms x (1 mole Kr)/(6.022 x 1023 Kr atoms) = 28 moles Kr (rounded to two sig figs)
The answer is 6,31 moles Ag.
The answer is 0,465 moles.
The answer is 3,587 moles.
Avogadro's number times 5.6 (or about 33.6 times ten to the 23rd power.
2.01x10^22 atoms x 1 mole/6.02x10^23 atoms = 0.0334 moles
In 3 moles of CH4, there are 18.06 x 10^23 times Hydrogen atoms.
1.20x10^24 atoms x 1 mole/6.02x10^23 atoms = 1.99 moles
