1.1a The scale of chemistry
Again using the figure, how many orders of magnitude larger is a bacterial cell than an aspirin molecule?
3 orders of magnitude
When one thing is ten times as large as another, it is said to be "an order of magnitude" larger. A hundred times larger is two orders of magnitude. A thousand is three orders of magnitude. By how many orders of magnitude is the Empire State Building taller than a chair seat? Enter an integer.
3 orders of magnitude
Examining the figure, how many orders of magnitude larger is a person than a bacterial cell?
6 orders of magnitude
A person is about 6 orders of magnitude larger than a cell. The cell is about 3 orders of magnitude larger than a molecule. By how many orders of magnitude is a person larger than a molecule?
9 orders of magnitude
How many times taller are most people than a piece of paper (measured on its long side)? Enter an integer.
People are 6 times taller than a piece of paper
