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
5,82 x 1023 atoms of tungsten equal 0,966 moles.
The answer is 1,21 moles.
9,003 x 1023 atoms of iron correspond to 1,495 moles.
2.45 X 1023 molecules CH2 (1 mole CH2/6.022 X 1023)= 0.407 moles CH2============
0.015 x 6.022 x 1023 = 9.033 x 1021
5,82 x 1023 atoms of tungsten equal 0,966 moles.
The answer is 1,21 moles.
9,003 x 1023 atoms of iron correspond to 1,495 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
0,25 moles F2
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
2.45 X 1023 molecules CH2 (1 mole CH2/6.022 X 1023)= 0.407 moles CH2============
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
Since a mole is 6.02 x 1023, 7.5 moles of Mn has (7.5 moles)(6.02 x 1023 parts/mole) = 4.5 x 1024 particles.
5.66 x 10^23 atoms of xenon is equal to 0.094 moles.
6,0221415 · 1023 x 6,0221415 · 1023
In one mole of a substance there are 6.0221415 x 1023 atoms.here we have 1.75 moles, so there will be 6.0221415 x 1023 x 1.75 molecules in this amount of gold.That will be 10.5387476 x 1023
