# How many copper atoms are in 5.6 moles of Cu_2O?

Mar 24, 2016

I found 6.74×10^(24) Cu atoms.

#### Explanation:

In one mole you have Avogadro's number (6.022×10^(23)) of objects, in this case 'formula units' of $C {u}_{2} O$.

So, in $5.6$ moles we have:

5.6×6.022×10^(23) formula units of $C {u}_{2} O$, each one with $2$ Cu atoms giving:

2×5.6×6.022×10^(23)=6.74×10^(24) atoms of Cu...
