Because the sun bleaches and destroys the melanin in your hair, and while it also destroys the melanin in your skin, your skin cells make more, causing your skin to get darker.
        
                    
             
        
        
        
The volume of HCl gas required to prepare the solution is 101.54 L
<h3>How to determine the mole of HCl </h3>
- Volume of solution = 1.25 L
- Molarity = 3.20 M
- Mole of HCl =? 
Mole = Molarity x Volume 
Mole of HCl = 3.2 × 1.25
Mole of HCl = 4 moles 
<h3>How to determine the volume of HCl </h3>
- Number of mole (n) = 4 moles 
- Temperature (T) = 30 °C = 30 + 273 = 303 K
- Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
- Gas constant (R) = 0.0821 atm.L/Kmol 
Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:
PV = nRT 
Divide both side by P
V = nRT / P
V = (4 × 0.0821 × 303) / 0.98
V = 101.54 L
