Hon many atoms are equal to 1.5 moles of hetium?

The  atoms   that are  equal  to 1.5  moles  of Helium  is 9.03 x 10^23  atoms    Explanation:  The  number of atoms is calculated  using the Avogadro's  law  constant that is according  to Avogadro's  law                              

1   moles =  6.02  x10^23 atoms                              

1.5 moles  = ?  atoms  by  cross  multiplication    

=  [(1.5  moles  x   6.02 x10^ 23  atoms)  /  1  moles)] =9.03  x10^23  atoms

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
