Question

How many moles are in 3.44 x 1028 particles of Cu?


a
5.71 x 1052 mol Cu

b
57,100 moles Cu
c
207 mols Cu
d
2.07 x 1024 mol Cu

Answer 1

Answer:

Explanation:

1 mole=6.02*10^23 particles[avogadro number of particles]

given, 3.44*10^28 particles ,implies

no of moles=3.44*10^28/6.02*10^23

                  =0.57*10^5=5.7*10^4 moles
