Question

A physical chemist measures the width of a molecule. The width is 72nm. What is the width in meters?

Answer 1

0.000000072 meters

Step-by-step explanation:

To convert nanometers (nm) to meters (m), you can use the following conversion factor:

1 meter (m) = 1,000,000,000 nanometers (nm)

So, to convert 72 nm to meters:

72 nm * (1 meter / 1,000,000,000 nm) = 0.000000072 meters

Therefore, the width of the molecule is 0.000000072 meters or simply 72 picometers (pm).
