Firstly, the equation you will use will be
Number of particles= number of moles x Avagadro's constant
so, given here is, number of moles and Ava's constant, thus
No. of particles = #0.8 xx 6.02 xx 10^23#= #4.8 xx 10^23#
Now, to calculate the number of atoms, this is what you do
Calculate the number of atoms you have in the given element or compound in the question
Copper is given, that means, 1 atom of copper
Now, multiply the number of atoms into the number of particles
#1 xx 4.8 xx 10^23#
That is, #4.8xx10^23# atoms in 0.8 moles of copper
Hope this helped
