The answer is 1,21 moles.
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.
2.45 X 1023 molecules CH2 (1 mole CH2/6.022 X 1023)= 0.407 moles CH2============
1 mole of O2 contains 6.02 x 1023 molecules. In 2.045 x 1021 molecules, there are ( 2.045 x 1021 / 6.02 x 1023 ) moles = 0.0034 moles.
Avagadros number states that there are 6.0221415 x 1023 atoms in a mole so 3.612 x 1023 molecules is just over half a mole 0.525 moles
Avogadro's number (Constant) is 6.022 x 1023 atoms or molecules per mole.So, simply divide the two.7.18 x 1023 / 6.022 x 1023 The two 1023's cancel out... and you get:7.18/6.022 = 1.19 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
9.02*1023 (molecules) divided by 6.022*1023 (molecules per mole) = 1.5 moles of ANY thing
2,22 1023 molecules of carbon dioxide is equal to 0,368 moles.
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
1 mole=6.02*1023 molecules or atoms5.23 moles=6.02*1023 * 5.23= {[(3.14846*1024molecules)]}
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.
0.943 moles H2O (6.022 X 1023/1 mole H2O) = 5.68 X 1023 molecules of water ========================
2.45 X 1023 molecules CH2 (1 mole CH2/6.022 X 1023)= 0.407 moles CH2============
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 mole of O2 has 6.023 x 1023 molecules. So, 23 moles of O2 will have 23 x 6.023 x 1023 molecules or 138.53 x 1023 molecules.
1 mole of O2 contains 6.02 x 1023 molecules. In 2.045 x 1021 molecules, there are ( 2.045 x 1021 / 6.02 x 1023 ) moles = 0.0034 moles.
