Question

How many copper atoms are in 70g of copper

Answer 1

`n = 6.634* 10^(23)\,atoms`

Step-by-step explanation:

The total amount of atoms is found by multiplying Avogradro's Number and the number of moles:

`n = \left(6.022* 10^(23)\,(atoms)/(mol) \right)\cdot \left((70\,g)/(63.546\,(g)/(mol) ) \right)`

`n = 6.634* 10^(23)\,atoms`
