Question

How many iron atoms are in 0.850 moles of iron

Answer 1

`5.12*10^2^3` atoms

Step-by-step explanation:

`0.85 moles Fe*(6.022*10^2^3)/(1 mole Fe) =5.12*10^2^3`

Use dimensional analysis to convert to moles by putting the moles of Fe (iron) on top and multiply by Avogadro's constant to cancel out moles and be left with atoms.
