Avogadro's number, 6.023 X 1023
The atomic number of an element tells you how many protons an atom of that element contains. This number is unique to each element and is found on the periodic table. The number of protons in an atom determines the element's identity.
There are approximately 6.022 x 10^23 atoms in 1 mol of chlorine, according to Avogadro's number.
There are 1 mol of oxygen atoms in 1 mol of CO2. Therefore, in 0.5 mol of CO2, there are 0.5 mol of oxygen atoms. Number of molecules = 0.5*6.022 *10^23 ≈ 3.011 *10^23 molecules
---- Golds molecular weight is 196.96 g/mol Thus, 1g of gold is (1g /196.96 g/mol) = 0.005 mol ---- 1 mol is 6.022 × 1023 atoms (Avogadro's Number) Thus, 0.005 mol is (0.005 mol x 6.022 × 1023 atoms/mol) = 3.057 x 1021 atoms ---- Therefore 1g of gold has APPROXIMATELY 3.057 x 1021 atoms
Well, the element you're dealing with doesn't matter. A mol is a constant number of measure, and is always equal to the same # of atoms. 1 mol= 6.022x10^23 of anything... You could have 1 mol of anything, and it will be the same, no matter what, because a mol is a number. So, to answer your question, 5.1 mols of potassium(or anything) has 3.07x1024 atoms.
1 mol of Ag and 1 mol of Au can be said to contain the same amount of atoms of each element.

1 mol Cu Atoms (6.02x10^23 atoms)
There are approximately 6.022 x 10^23 atoms in 1 mol of chlorine, according to Avogadro's number.
There are 1 mol of oxygen atoms in 1 mol of CO2. Therefore, in 0.5 mol of CO2, there are 0.5 mol of oxygen atoms. Number of molecules = 0.5*6.022 *10^23 ≈ 3.011 *10^23 molecules
---- Golds molecular weight is 196.96 g/mol Thus, 1g of gold is (1g /196.96 g/mol) = 0.005 mol ---- 1 mol is 6.022 × 1023 atoms (Avogadro's Number) Thus, 0.005 mol is (0.005 mol x 6.022 × 1023 atoms/mol) = 3.057 x 1021 atoms ---- Therefore 1g of gold has APPROXIMATELY 3.057 x 1021 atoms
There are 1 mol of phosphorus atoms in 1 mol of copper (II) phosphate. Therefore, in 3.30 mol of copper (II) phosphate, there are 3.30 mol of phosphorus atoms, which is equivalent to 3.30 x 6.022 x 10^23 = 1.97 x 10^24 atoms of phosphorus.
It is always the same - Avagadro's number. 6.022 x 1023 atoms per gram mole.

0.250 X Avogadro's Number = 1.51 X 1023, to the justified number of significant digits.
In NaCl, the ratio of sodium to chloride atoms is 1:1. Therefore, in 2.35 mol of NaCl, there are 2.35 mol of sodium atoms. To find the number of sodium atoms, you would multiply the number of moles by Avogadro's number (6.022 x 10^23).
