Question

How many moles are in 6.73 x 10^24 atoms of Cu?

Answer 1

To find out how many moles are in 6.73 x 10^24 atoms of Cu, divide the number of atoms by Avogadro's number, resulting in approximately 11.18 moles of Cu.

Step-by-step explanation:

To determine how many moles are in 6.73 x 10^24 atoms of Cu (copper), we use Avogadro's number, which is 6.022 × 10^23 atoms per mole. The number of moles (n) can be calculated using the formula n = number of atoms / Avogadro's number. Given the number of copper atoms, the calculation is as follows:
n = (6.73 × 10^24 atoms Cu) / (6.022 × 10^23 atoms/mol) = 11.18 moles Cu

This means there are approximately 11.18 moles of copper in 6.73 x 10^24 atoms of Cu.

Answer 2

Here is the work, and this will work with any element:

Using the constant 6.022x10^23 for numbers of atoms per mole, we can solve using this simple equation:

Number of atoms of element / mol constant = moles of element

So for this it would be:

6.73 x 10^24 atoms Cu / 6.022 x 10^23 atoms/mol

The atoms cancel and you are left with 11.2 mol Cu
