6.022 X 1023 - 6.022 X 1022 = 5.419 X 1023 ======================
It equals: 3.01 times 1023 = 3100.3
6567.66
33 with 8 remaining 602 - 8 = 594 = 18 x 33
6178.92
602 = (6 x 100) + (0 x 10) + (2 x 1)
6.022 X 1023 - 6.022 X 1022 = 5.419 X 1023 ======================
1 mole of molecules = 6.022 x 1023 molecules 0.536mol x 6.022 x 1023 molecules/mol = 3.28 x 1023 molecules
6.022 x 1023 is Avogadro's Number.
6.0221367 × 1023 Or (less sensibly) 602 213 670 000 000 000 000 000
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
1 mole C4H10 = 58.1222g = 6.022 x 1023 molecules 11.7g C4H10 x 6.022 x 1023 molecules/58.1222g = 1.21 x 1023 molecules C4H10
6.02 *1023 is a quantity called a mole.
It equals: 3.01 times 1023 = 3100.3
Avogadro's number. I will show you. 18.02 grams water (1 mole H2O/18.016 grams)(6.022 X 1023/1 mole H2O) = 6.021 X 1023 atoms of water ----------------------------------------
There are 4.53 x 10^23 atoms in 0.75 moles of neptunium. This is because one mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23.
