Respuesta :

1. Identify the given

• Number of particles in Cu = 6.73x10^24

• Number of moles= x?

• We know that 1 mole of copper = 6.023 x 10^23 atoms

2. Calculate moles

number of moles = 6.73x10^24 /6.023 x 10^23

= 11.179

≈11.18 moles of Cu

This means that option B is correct, we have 11.18 moles Cu in 6.73x10^24 Cu particles.
