Question

One molecule of the spherically shaped, oxygen‑carrying protein in red blood cells, hemoglobin, has a diameter of 5.5 nm . What is this diameter in meters?

Answer 1

`5.5*10x^(-9)m`

Step-by-step explanation:

As you have the diameter of the sphere in nanometers (nm), you need to use de conversion factor to find the diameter in meters (m):

First you should put the quantity that you want to convert with its respective units:

`Diameter=5.5nm`

Then you put the conversion factor, always you should put the same unit that you want to convert in the denominator:

Diameter =
`5.5nm*(1*10^(-9)m)/(1nm)`

And finally, you should multiply and/or divide the quantities:

Diameter =
`5.5*10^(-9)m`
