No of atoms = no of moles x Avogadro's no
= 6.21 x 6.023 x 1023
The number of atoms in 0.40 mole of ANY element or compound is: 0.40 mol x 6.022x1023 atoms/mol = 2.4x1023 atoms.
To find atoms in number of moles you multiply by avogadra's number (6.022x10^23) then multiply by the number of atoms, in this case it is one because carbon is a monotomic element. The answer is 9.03x10^23 atoms C

The number of atoms is 39,746.10e23.
3 moles of Zn is equal to 18.09x1023 atoms. I used Avogadro's Number : 6.03x1023 particles/mol This number is the number of atoms or molecules in a mol of any substance. 3 moles X 6.03x1023 particles/mol = 18.09x1023 atoms
The number of atoms of nitrogen of 0,755 mol of N2 is 4,546716347035.10e23.
To calculate the number of atoms in 13.2 mol of copper, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Multiply 13.2 mol by Avogadro's number to get the number of atoms: 13.2 mol * (6.022 x 10^23 atoms/mol) = 7.93 x 10^24 atoms. Therefore, there are approximately 7.93 x 10^24 atoms in 13.2 mol of copper.
To find the number of sulfur atoms in a given mass of sulfur, you can use the following steps: Determine the number of moles of sulfur using the formula: moles = mass molar mass moles= molar mass mass Given that the molar mass of sulfur ( S S) is 32.06 g/mol and the mass ( m m) is 1.56 g: moles = 1.56 g 32.06 g/mol moles= 32.06g/mol 1.56g Once you have the moles of sulfur, you can use Avogadro's number (6.022 x 1 0 23 10 23 mol − 1 −1 ) to find the number of atoms: number of atoms = moles × Avogadro’s number number of atoms=moles×Avogadro’s number Let's calculate it: moles = 1.56 g 32.06 g/mol ≈ 0.0488 mol moles= 32.06g/mol 1.56g ≈0.0488mol number of atoms = 0.0488 mol × ( 6.022 × 1 0 23 mol − 1 ) number of atoms=0.0488mol×(6.022×10 23 mol −1 ) number of atoms ≈ 0.0488 × 6.022 × 1 0 23 number of atoms≈0.0488×6.022×10 23 number of atoms ≈ 3.0 × 1 0 22 number of atoms≈3.0×10 22 Therefore, there are approximately 3.0 × 1 0 22 3.0×10 22 sulfur atoms in 1.56 g of sulfur.
The number of atoms in 0.40 mole of ANY element or compound is: 0.40 mol x 6.022x1023 atoms/mol = 2.4x1023 atoms.
To find atoms in number of moles you multiply by avogadra's number (6.022x10^23) then multiply by the number of atoms, in this case it is one because carbon is a monotomic element. The answer is 9.03x10^23 atoms C
Avagadro's number = 6.022 × 1023 atoms/mol0.5 mol × (6.022 × 1023) atoms/mol = 3.011 ×1023 atoms
The number of atoms is 9,0332112855.10e23.
The number of carbon atoms which are present in 0,062 mol acetic acid HC2H3O2 is 0,747.10e23.
