The radius of a lead atom is 175 pm. How many lead atoms would have to be laid side by side to span a distance of 4.20 mm?

wouldn't you divide the 4.20mm by 175pm?

Normally, you need to convert both to meters.

However, technology is on the side of laziness, so paste this in the Google window and press return

4.20mm/175pm
