follow the avagardo number
here,
2.60x10^23 molecules of H2O X 1mole
-------
6.02x10^23 molecule of H2O ( molecule of H2O cancel and just remain with mole )
so,
2.60x10^23
----------------- moles
6.02x10^23
your final product wii be 0.43 mole of H20

One mole is 6.02 × 1023 molecules. So 2 molecules out of that 6.02 × 1023 would be 2/(6.02 × 1023) or 3.32 ×10-24 moles.
The answer is 1,21 moles.
2.45 X 1023 molecules CH2 (1 mole CH2/6.022 X 1023)= 0.407 moles CH2============
1.46 moles CaCl2 (6.022 X 1023/1 mole CaCl2) = 8.79 X 1023 molecules of calcium chloride ================================
3 x 6.022 x 1023 = 18.066 x 1023 = 1.8066 x 1024
0.943 moles H2O (6.022 X 1023/1 mole H2O) = 5.68 X 1023 molecules of water ========================
One mole is 6.02 × 1023 molecules. So 2 molecules out of that 6.02 × 1023 would be 2/(6.02 × 1023) or 3.32 ×10-24 moles.
1 mole of molecules = 6.022 x 1023 molecules 1.25 moles of molecules x 6.022 x 1023 molecules/mol molecules = 7.53 x 1023 molecules
Avogadro's Number = Avogadro's number = 6.0221415 × 10236.02×1023 (abbreviated); this is the number of atoms, ions, molecules, or anything else in 1 mole. 0.33 moles of water would have 0.33·6.02×1023 = 1.99×1023 molecules. However water's formula is H2O, so it has 3 atoms per molecule. (0.33 moles) × (6.02×1023 molecules per mole) = 1.99×1023 molecules.1.99×1023 molecules × 3 atoms per molecule = 5.96×1023 atoms(0.33 moles) × (6.0221415 × 1023molecules per mole) = 1.987306695×1023 molecules.1.987306695×1023 molecules × 3 atoms per molecule =5.961920085 1023 atomsI would use the rounded answer, 5.96×1023 atoms
Since 1 mole is (6.022×1023 molecules)/(mol), so 9.02 x 1023 molecules would be 1.4978... mol
The value is 1,328.10e-3 moles.
9.02*1023 (molecules) divided by 6.022*1023 (molecules per mole) = 1.5 moles of ANY thing
The given number is 299 x1021=2.99 x 1023 one mole has 6.022 x 1023 molecules. Therefore, no. of moles= 2.99 x 1023/6.022 x 1023 = .496 moles
MolesOne mole is 6.02 × 1023 of anything. One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes. You get the picture? One mole of molecules is 6.02 × 1023 molecules.
1.81018 divided by Avogadro constant, 6.02 x 1023 answer : 3.0059 x 10-24
2,22 1023 molecules of carbon dioxide is equal to 0,368 moles.
