Cesium atoms are the largest of the naturally occurring elements. they have a diameter of 5.30 1010 m. calculate the number of cesium atoms that would have to be lined up to give a row of cesium atoms 2.54 cm (1 in.) long.

Explanation:

First we need to match the units of both measures, let's make meters for both of them, so:

Now we need to make a relation between both measures, as we know that the first distance is:

Then:

1.solid

2.carbon dioxide

3.helium
