1.45*10^(-17)M*(6.023*10^23 atoms/mole)
The number of atoms is 8,733.10e6.
1.45
In one mole of Arsenic contains 6.02 x 10^23 atoms. This is the Avogadro's number. So in 3.5 moles of Arsenic, there would accordingly be 2.11 x 10^24 atoms.A mole of As has the Avogadro number of moles. It is equivalent to 6.022 x 10^23. Therefore, 3.5 moles of the element contains 2.11 x 10^24 atoms of Arsenic.
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.
0.75 mole of carbon atoms (6.022 X 1023 /1 mole C x 0.75) = 4.52 X 1023 carbon atoms
1 mole NH3 (3 mole H/1 mole NH3) = 3 mole hydrogen atoms
2.80x10^24 atoms x 1 mole/6.022x10^23 atoms = .465x10^1 mole = 4.65

Using your molar mass. 0.0001 grams silver (1 mole Ag/108 grams)(6.022 X 1023/1 mole Ag) = 5.58 X 1017 atoms of silver =====================
1 mole = 6.022e23 atoms 8.25 mole = 4.96815 e 24 atoms
I assume you mean grams of aluminum. 4.1 X 10 -5 grams aluminum (1 mole Al/26.98 grams)(6.022 X 1023/1 mole Al) = 9.2 X 1017 atoms of aluminum ------------------------------------------
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
