Question

A water molecule is about 0.0000000021 meters wide.DNA is about 0.00000002 meters wide which is wider??​

Answer 1

The DNA is wider

Explanation:

So I had counted them and figured out that for the water molecule has 8 zero's while the DNA one has 7 zero's. Then I did the math, 8-7, which equals 1. This means that the DNA has 1 less fewer zero than the other, meaning that it's wider than the molecule
