The distance between the centers of neighboring gold atoms is 2.9 * 10 (-10) m. How many atoms will fit along the thickness of a 0.1 micron thick piece of gold?

To solve this problem, we first of all need to convert micrometers to meters. Recall that the prefix mk (micro) means 10-6

respectively 0.1μm = 1 * 10 ^ -7.

For a further solution, we just need to recall the formula and make arithmetic calculations, we get: N = (1 * 10 ^ -7) / (2.9 * 10 ^ -10) = 344
