Answer:
               10.87 g of Ethyl Butyrate
Solution:
The Balance Chemical Equation is as follow,
    H₃C-CH₂-CH₂-COOH + H₃C-CH₂-OH  →  H₃C-CH₂-CH₂-COO-CH₂-CH₃ + H₂O
According to equation,
     88.11 g (1 mol) Butanoic Acid produces  =  116.16 g (1 mol) Ethyl Butyrate
So,
            8.25 g Butanoic Acid will produce  =  X g of Ethyl Butyrate
Solving for X,
                       X  =  (8.25 g × 116.16 g) ÷ 88.11 g
                       X  =  10.87 g of Ethyl Butyrate
 
        
             
        
        
        
The molarity of a hydrochloric acid solution : 0.32 M
<h3>Further explanation  </h3>
Titration is a procedure for determining the concentration of a solution by reacting with another solution which is known to be concentrated (usually a standard solution). 
Titrations can be distinguished including acid-base titration, depositional titration, and redox titration. An acid-base titration is the principle of neutralization of acids and bases is used.  
Acid-base titration formula  
Ma. Va. na = Mb. Vb. nb  
Ma, Mb = acid base concentration  
Va, Vb = acid base volume  
na, nb = acid base valence  
1 ⇒HCl (valence=1, HCl ⇒H⁺+Cl⁻, one H⁺) 
2⇒Ca(OH)₂(valence=2, Ca(OH)₂⇒Ca²⁺+2OH⁻, two OH⁻)
M₂=0.1 M
V₂=48 ml=0.048 L
V₁=30 ml=0.03 L

 
        
             
        
        
        
It is a solution, because it's the alloy of tin and copper 
        
             
        
        
        
B. Precipitates are formed when two solutions combine to form another solution and a solid.
