Amount of moles in 3.34x10^34 formula units of cu(oh)2

 The amount of  moles in  3.34 x10³⁴  formula unit of Cu(OH)₂ is 5.55 × 10¹⁰  moles

  calculation

 The  amount  of  moles  is calculated  using  the Avogadro's  law   constant

That  is  1  moles =  6.02 × 10²³  formula units

                 ? moles = 3.34 × 10³⁴ formula  units

by cross  multiplication

= {1 mole  ×3.34 ×10³⁴  formula units ] / 6.02 × 10²³ formula units}  = 5.55 ×10¹⁰  moles

it's c. elements are placed in rows based on how may valencies electrons have.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
