How many moles are in a sample of 4.57 x 1024 atoms of neon (Ne)? 7.59 mol Ne
27.5 mol Ne
91.4 mol Ne
151 mol Ne

Can someone please explain how you divide 4.57 x 10^24 by 6.022 x 10^23?? Thank you

  super sorry but i dont know lo

Do you have any options for this question?

Answeropposite;

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
