How many moles of cobalt (Co) atoms are there in
6.00x10^9 (6 billion) Co atoms?

9.9vogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. Calculation are as follows:

6.00x10^9 Co atoms x ( 1 mol Co / 6.022 x 10^23 atoms Co ) = 9.96 x 10^-15 mol Co

The number of moles should be [tex]9.96 \times 10^{-15} mol Co[/tex]

Calculation of a number of moles:

Avogadro's number shows the number of units in one mole of any substance.

This has the value of [tex]6.022 \times 10^{23}[/tex] units/mole.

Now the computation should be

[tex]= 6.00\times 10^{9}Co\ atoms \times ( 1 mol Co / 6.022 \times 10^{23} atoms Co )[/tex]

= [tex]9.96 \times 10^{-15} mol Co[/tex]
