One mole of Strontium is Avagadro's Number of Strontium atoms, or 6.0221409 x 10^23 atoms
Therefore 0.68 moles is that number multiplied by 0.68, or 4.09505578276 x 10^23 atoms
Therefore 0.68 moles is that number multiplied by 0.68, or 4.09505578276 x 10^23 atoms

1 moles of Sr contains 6.022 × 10²³ Sr atoms.
No. of Sr atoms = (6.022 × 10²³ atoms/mol) × (0.68 mol) = 4.1 × 10²³ atoms
No. of Sr atoms = (6.022 × 10²³ atoms/mol) × (0.68 mol) = 4.1 × 10²³ atoms

6.0221x 10^23 atoms / 1 mole of Sr x 0.68 mole of Sr = 4.095 x 10^23 atoms of Sr in 0.68 mole of Sr

you didnt say what atoms, but in strontium case, the relative atomic mass is 87.62. you work the rest out

1 mole of any monoatomic element has 6.023 x 10^23 atoms.
In this case there are 0.68 x 6.023 x 10^23 atoms.
In this case there are 0.68 x 6.023 x 10^23 atoms.
