Context: I love math, and am very good at math; however, it's been a few years since I have taken a college math course, and am therefore pretty rusty on my math skills. I feel really dumb at the moment, considering this looks like a basic math question and I have taken Calculus 1 & 2, but for some combination of reasons I'm just stumped and have no idea how to solve this.

What I've Tried: Given the answer needs to be in kg, I converted 3 g/dL to 0.003 kg/dL. I also calculated the weight of the blood = 8% of 75 kg = 0.08(75 kg) = 6 kg. Like I mentioned above, I have no idea what else to do from here, nor do I understand the significance of the mention of the specific gravity of blood.

Problem: As discussed in class, we often need one type of "globulin" or another to help transport a subset of hormones through our circulatory system. It is estimated that a normal level of globulin in the blood is 3 g/dL. Let's say a person weighs 75 kg. Further, we know that 8% of one's body weight is blood (assume that blood has a specific gravity of 1). Given these parameters, what is the total weight of globulins in this person's blood (provide your answer in kg)?
 
I'm guessing specific gravity is used to convert weight of the blood to volume. Then you can use the 3 g/dL conversion factor.
 
How much blood does this person have, first in kg and then in dL? Then how much globulin would be in that?

Let us know what you've done with our suggestions, so we can either confirm, correct, or complement what you are doing.

(assume that blood has a specific gravity of 1)

That means:

1 deciliter of blood (dl - dcl) = 0.10 kilograms of blood (kg wt.)
