Question

THe diameter of an atom is about 10-10m. Howmany atoms make a millionth of a meter (10-6m)long? How many atoms cover a square a millionth of a meter ona side? How many atoms fill a cube a millionth of a meter ona side? If there were a dollar on each atom what could youbuy with the money you had?

Explanation / Answer

                            the diameter of the atom is D = 10-10m                      so the radius of the atom is R = D / 2 let the number of the atoms make 10-6m be n then we have                                    n *10-10 m = 10-6 m                                       n =    10000     n2 many atoms cover asquare a millionth of a meter on a side i.e 108 atoms      n3 many atoms fill acube a millionth of a meter on a side i.e 1012 atoms
