Question

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

Answer 1

Answer : The diameter in meters is, $5.5\times 10^{-9}m$

Explanation :

As we are given that the diameter of red blood cells is, 5.5 nm. Now we have to convert it into meter.

The conversion used from nanometer to meter is:

$1nm=10^{-9}m$

As, $1nm=10^{-9}m$

So, $5.5nm=\frac{5.5nm}{1nm}\times 10^{-9}m=5.5\times 10^{-9}m$

Thus, the diameter in meters is, $5.5\times 10^{-9}m$
