Question- The diameter of a neutral helium atom is about 164pm. Suppose we could line up helium atoms side by side in contact with one another. Approximately how many atoms would it take to make the distance 1 cm from end to end? Please I need to see how it is worked. Round to the nearest whole number also.

Thank you! My final is tomorrow and I am in desperate need!
