6.022 x 1023 is Avogadro's Number.
5,51025128 × 1023
20010 = 102,400,000,000,000,000,000,000 = 1.024 x 1023
6.022 x 1023 atoms comprise just about 1 mole. 1.11 moles is greater than 1 mole.
When 6.02 x 1,023 is multiplied by 9.1 x 10-31 the product is what?The answer is: 1,176,881.706
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.
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
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.
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
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
