5.6 X 10^-3
I will show you that one as they are all the same. ( no variance by species )
5.6 X 10^-3 moles C (6.022 X 10^23/1 mole C)
= 3.4 X 10^21 atoms of carbon
3.22e23 atoms
There are 6.02 x 10 ^ 23 atoms or molecules of a substance in one mole of that substance. This is Avogadro's number.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
1 mole H2SO4 x 4 moles O/mole H2SO4 x 6.02x10^23 atoms of O/mole O = 2.4x10^34 oxygen atoms
6.02214076×1023
1 mole = 6.022e23 atoms 8.25 mole = 4.96815 e 24 atoms
1 mol of anything = 6.022x1023 atomsso 1.4 mole = 1.4 * 6.022x1023 atoms / mole = 8.4308x1023 atoms
3.22e23 atoms
There are 6.02 x 10 ^ 23 atoms or molecules of a substance in one mole of that substance. This is Avogadro's number.
A mole is a counting unit of molecules. Since sodium is an element and is exists by itself one mole of sodium will equal one mole of atoms or 6.02 x 1023 atoms.
0.0602 mole K x 6.02x10^23 atoms/mole = 3.62x10^22 atoms
0.75 mole of carbon atoms (6.022 X 1023 /1 mole C x 0.75) = 4.52 X 1023 carbon atoms
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
0.0384 moles K x 6.02x10^23 atoms/mole = 2.31x10^22 atoms
1 mole of any element = 6.02 × 1023 atoms
1 mole H2SO4 x 4 moles O/mole H2SO4 x 6.02x10^23 atoms of O/mole O = 2.4x10^34 oxygen atoms
1 mole NH3 (3 mole H/1 mole NH3) = 3 mole hydrogen atoms
