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

(5.5L)(\frac{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=\frac{(15 g)(5500mL)}{100mL} =825g

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

(825g)(\frac{1kg}{1000g} )=0.825kg

Using stoichiometry:

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

Using these metal ion/metal standard reduction potentials calculate cell potential for Cu2+(aq) + Cd(s) →Cd2+(aq)+ Cu(s) Cu2+(aq
Katena32 [7]

Solution :

Cd(s) ---------------------->  Cd^{+2} (aq) + 2e^-      ,     E_0  =   0.34 v

Cu^{+2}  (aq)  +   2e^-  ------------> Cu (s)             ,     E_0  =  -0.04 v

----------------------------------------------------------------------------------------------

Cd(s)  +  Cu^{+2}  (aq)  ------------->  Cd^{+2} (aq)  +  Cu (s)   ,      E_0  =  0.30 v  

The cell potential is defined as the measure of \text{ potential difference }  between the \text{two half cells} of an electrochemical cell.
