Question

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

Answer 1

Using stoichiometry:

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

Answer 2

there are 0.825 kg in 5.5 l of blood

Step-by-step explanation:

First, we have to convert L into mL so we work with the same units

`(5.5L)((1000mL)/(1L)) =5500 mL`

Using a rule of three we have:

15 g of hemoglobin ------> 100 mL of blood

x ------> 5500 mL of blood

`x=((15 g)(5500mL))/(100mL) =825g`

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

`(825g)((1kg)/(1000g) )=0.825kg`
