6.022 X 1023 - 6.022 X 1022 = 5.419 X 1023 ======================
It equals: 3.01 times 1023 = 3100.3
6567.66
6178.92
33 with 8 remaining 602 - 8 = 594 = 18 x 33
602 = (6 x 100) + (0 x 10) + (2 x 1)
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
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
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
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
0.660 x 6.022 x 1023 = 3.97452 x 1023 atoms
1.2 moles oxygen x 6.022 x 1023 = 7.2264 x 1023
1 mole H2O = 6.022 x 1023 molecules 0.357mol H2O x 6.022 x 1023 molecules/mol = 2.15 x 1023 molecules H2O
14 grams of nitrogen have 6.023 x 1023 atoms So 2.2 grams will have (6.023 x 1023 x 2.2)/14 = 29.15 x 1023 atoms
