1.20x10^24 atoms x 1 mole/6.02x10^23 atoms = 1.99 moles
Convert 1.35 × 1024 atoms of carbon to moles of carbon
2.7×1024 atoms
(2.16x10^24 atoms) x ( 1 mole/ 6.022x10^23 atoms) = 0.3586848223x10^1 which your answer should be 3.59 moles
2.26*1024
2.1 X 1024 atoms (1 mole/6.022 X 1023) = 3.5 moles ========
(1.2 x 1048)/Avogadro's number = 2.0 X 1024 moles. (I hope the questioner has a large storehouse!)
The number of moles is 0,528.
Convert 1.35 × 1024 atoms of carbon to moles of carbon
How many moles are there in 9.0333x1024 atoms of helium
2,80 1024 atoms of silicon equals 0,465 moles.
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.
5 mole copper (6.022 X 1023/1 mole Cu) = 3 X 1024 atoms of copper -----------------------------------
1,67.1024 argon atoms is equal to 2,773 moles.
The answer is 15,2 moles.
4.0 moles Cu (6.022 X 1023/1 mole Cu) = 2.4 X 1024 atoms of copper ====================
4.66715966 × 1024
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
