How many atoms are there in a 5.2-g copper

There are copper atoms in 5.2 gram of metallic copper.

Step-by-step explanation:

Start by finding the number of moles of copper atoms in that 5.2 gram of metallic copper. Look up the relative atomic mass of copper on a modern periodic table.

In other words, the mass of one mole of copper atoms is 63.546 gram.

.

How many moles of copper atoms in that 5.2 gram sample?

.

Now, how many atoms is ?

The Avogadro's Number gives the number of particles in one mole:

. (Encyclopedia Britannica)

There are particles (a very large number) in one mole. of copper atoms will thus contain

copper atoms.

the answer is simply just 6n add the two together as they have an n
