Question

A xenon atom has a diameter of approximately 216 pm. If xenon atoms were

placed into a straight line, how many would it take to span a distance of 1 inch?
How many moles of xenon atoms would that be? (1 pm = 1 x 10-12 m; 1 in =
0.0254 m)

A) 1.18 x 108 atoms/in
1.95 x 10-16 mol

B) 2.36 x 108 atoms/in
9.75 x 10-17 mol

C) 1.18 < 1010 atoms/in
1.95 x 10-14 mol

D) 2.36 1010 atoms/in
9.75 × 10-15 mol

Answer 1

I think A A) 1.18 x 108 atoms/in

1.95 x 10-16 mol
