a normal hemoglobin concentration in the blood is 15g/100ml of blood how many kilogram of hemoglobin are in a person who has 5.5
l of blood
2 answers:
Answer:
there are 0.825 kg in 5.5 l of blood
Explanation:
First, we have to convert L into mL so we work with the same units

Using a rule of three we have:
15 g of hemoglobin ------> 100 mL of blood
x ------> 5500 mL of blood

As the answer must be in kilogram we must convert grams into kilograms:

Using stoichiometry:
5.5 L of blood x (1000 mL/1L) x (15 g/100 mL) x (1 kg/1000 g) = 0.825 kg
