4,515.10e24 atoms of magnesium is equal to 7,5 moles.
5.75x10^24 atoms x 1 mole/6.02x10^23 atoms = 9.55 moles of Al
2.854x10^24
1.8x10*24
If you meant 8.9 * 10^24, then there are 14.78 moles. 8.9 e24 (# of atoms) / 6.02 e23 (# of atoms in a mole) = 14.78 (# of moles)
4,515.10e24 atoms of magnesium is equal to 7,5 moles.
1.81x10^24 atoms
5.75x10^24 atoms x 1 mole/6.02x10^23 atoms = 9.55 moles of Al
1 mol Cr/6.02x10^23 atoms x 3.6x10^24 atoms = 5.98 moles
3,00 moles of Li have 18,066422571.10e23 atoms.
2.80x10^24 atoms x 1 mol/6.02x10^23 atoms = 4.65 moles
The answer is 3,587 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
2.854x10^24
1.8x10^24 atoms of N
1.8x10*24
1.20x10^24 atoms x 1 mole/6.02x10^23 atoms = 1.99 moles
