The formula for converting is: atoms ÷ Avogadro's constant = # moles (1.8 × 1023) ÷ (6.02 × 1023)= 0.299 moles Cu
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
In 3 moles of CH4, there are 18.06 x 10^23 times Hydrogen atoms.
10 moles of oxygen atoms or 5 moles of oxygen molecules.
1 mole of silver contains 6.022 X 10^23 atoms 62 moles of silver contains 3.73 X 10^25 atoms of silver
Ca!
Take that number of copper atoms and divide by "Avogadro's constant," which is the number of representative particles (in this case, atoms) in 1 mole of any substance. Here's the math: 1.8x10e24 / 6.02x10e23 = approximately 3 moles.
The atomic weight of copper is 63.546 grams per mole. 129 kg is equal to 129000 grams. So there are 2030.03 moles of copper. There are 6.022 x 10^23 copper atoms in a mole. So there are 12.22 x 10^26 atoms.
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
3.4 mole Cu (6.022 X 10^23/1mol Cu ) = 2.047 X 10^23 atoms of copper.
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.
2.36 moles x 6.022*10^23 atoms/mole. Moles cancel and you are left with 1.42*10^24 xenon atoms.
1.50 x 10 to the 23 atoms of fluorine is equal to 0,249 moles.
The answer is 3,587 moles.
In a mole there is 6.022 x 1023 atoms. In two moles there are twice that amount.
Approx 7.925*10^23 atoms.
1 mol Cr/6.02x10^23 atoms x 3.6x10^24 atoms = 5.98 moles
2.09 moles Sn (6.022 X 10^23 atoms / 1 mole Sn) = 1.26 X 10^24 atoms of tin
