Answer:
π = 14.824 atm
Explanation:
wt % = ( w NaCL / w sea water ) * 100 = 3.5 %
assuming w sea water = 100 g = 0.1 Kg
⇒ w NaCl = 3.5 g
osmotic pressure ( π ):
∴ T = 20 °C  + 273 = 293 K
∴ C ≡ mol/L
∴ density sea water = 1.03 Kg/L....from literature
⇒ volume sea water = 0.1 Kg * ( L / 1.03 Kg ) = 0.097 L sln
⇒ mol NaCl = 3.5 g NaCL * ( mol NaCL / 58.44 g ) = 0.06 mol
⇒ C NaCl = 0.06 mol / 0.097 L = 0.617 M
⇒ π = 0.617 mol/L * 0.082 atm L / K mol * 293 K
⇒ π = 14.824 atm
 
        
             
        
        
        
<h2>Answer:</h2>
Rutherford's models 
<h2>Explanations:</h2><h2>What is the electron cloud model?</h2>
There are known as the region where electrons are found especially in the nucleus.
According to the five basic atomic models which have contributed to the structure of the atom itself, the Rutherford's models of the atom include a structure that is mostly made of empty space compared to thomson that proposed the plum pudding model of the atom

Answer:
 is the concentration of the compound in a solution.
 is the concentration of the compound in a solution.
Explanation:
Using Beer-Lambert's law :
Formula used :

Where:
A = absorbance of solution
C = concentration of solution 
l = path length
 = molar absorptivity coefficient
 = molar absorptivity coefficient
We have:
C = ? , l = 1.00 cm, A = 0.090



 is the concentration of the compound in a solution.
