642 x 3 = 1926
6.022 X 1023 - 6.022 X 1022 = 5.419 X 1023 ======================
77,040 because 107 x 2 = 214 214 x 3 = 642 642 x 4 = 2568 2568 x 5 = 12840 12840 x 6 = 77040
It equals: 3.01 times 1023 = 3100.3
6178.92
642 x 3 = 1926
The prime factorization of 642 is 2 x 3 x 107.
164,994
1 x 642, 2 x 321, 3 x 214, 6 x 107.
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.
77,040 because 107 x 2 = 214 214 x 3 = 642 642 x 4 = 2568 2568 x 5 = 12840 12840 x 6 = 77040
0.660 x 6.022 x 1023 = 3.97452 x 1023 atoms
