Moles of Zn in 5.6*10^24 atoms of Zn
1 answer:
1 mole of any substance (atoms or molecules)=6.022 x 10²³ atoms or molecules.
In this case:
1 mole of Zn=6.022*10²³ atoms.
Then:
1 mole of Zn---------------------6.022*10²³ atoms
x-------------------------------------5.6*10²⁴ atoms
x=(1 mole of Zn * 5.6*10²⁴ atoms)/6.022*10²³ atoms=9.0032... moles≈
≈9 moles
Answer: we have 9 moles in 5.6*10²⁴ atoms of Zn.
