We have been given that there were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate.
So the number of volunteers that donated blood will be 32-n.
We are also told that the rest of the volunteers donated 470 milliliters each.

Therefore, each of the volunteers donated millimeters of blood.
