1. Neutron mass: The question states "if the neutron same as..." but doesn't complete the thought. It seems like it's trying to compare the neutron mass to something, but it's unclear what.

2. Copper atoms: The question asks how many copper atoms are in 1 kg of copper. This part is solvable, but the proton/electron information is irrelevant.

Let's address the second part of the question:

To find the number of copper atoms in 1 kg, we need to know:

* Molar mass of copper: Copper has a molar mass of 63.546 g/mol.

* Avogadro's number: This tells us the number of atoms in one mole of any substance, which is approximately 6.022 x 10^23 atoms/mol.

Calculation:

1. Convert kg to grams: 1 kg = 1000 g

2. Find moles of copper: 1000 g / 63.546 g/mol = 15.74 mol

3. Calculate the number of atoms: 15.74 mol * 6.022 x 10^23 atoms/mol = 9.48 x 10^24 atoms

Therefore, there are approximately 9.48 x 10^24 copper atoms in 1 kg of copper.

To clarify the question about the neutron, please provide more information about what you want to compare it to.
