You need to collect blood from a dog donor for a blood transfusion. This dog weighs 100 pounds and is healthy and in normal body condition. Calculate the maximum volume of blood you can safely collect from this dog right now.  Be sure to include correct units when reporting your final answer. You do not have to show your work to receive full credit for your response; however, I can only give partial credit if you do show your work. 🙂
