The number of moles = 0.5
Further explanation
Given
3.01 x 10²³ atoms Cu
Required
moles
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
Input the value :
n = N : No
n = 3.01 x 10²³ : 6.02.10²³
n = 0.5
