This is a poorly worded question. A mole of Sears Towers would, by definition, contain 6.022 x 10^23 Sears Towers, because a mole of anything contains Avogadro’s number many of it. But because the height of Sears Tower is given, it seems to imply that the question is really asking “How many Sears Towers are in a mole of feet of skyscraper?” In that case, divide Avogadro’s number by the given number of feet.

Just be happy with one..

That’s like asking “How many eggs in a dozen (eggs)?”, or “How many Sears Towers in a dozen (towers)”

Doesn’t matter what the object is, a dozen is always 12, and a mole is always 6.022 x 10^23.

6.022 x 10^23…

doesn’t matter what the ht size or shape is…

one mole of anything is 6.022 x 10^23 units of it…..rest is irrelevant

1 mole = 6.022×10^23 of anything

1 mole of sears towers = 6.022×10^23 sears towers.

if you want to know how many feet that is end to end…

6.022×10^23 x 1707 ft = 1.03×10^27 ft

*********
that’s a very large number….

1.03×10^27 ft x (1 mi / 5280 ft) x (1 light year / 5.87×10^12 mi) = 33 billion light years.

the universe is believed to be 93 billion light years in diameter. so a mole of sears towers stacked end to end would reach about 1/3 of the way across the universe
