Answer:
0.208mole of CO2 
Explanation:
First, let us calculate the number of mole of HC3H3O2 present. 
Molarity of HC3H3O2 = 0.833 mol/L
Volume = 25 mL = 25/100 = 0.25L
Mole =? 
Mole = Molarity x Volume 
Mole = 0.833 x 0.25 
Mole of HC3H3O2 = 0.208mole 
Now, we can easily find the number of mole of CO2 produce by doing the following:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
From the equation, 
1mole of HC2H3O2 produced 1 mole of CO2.
Therefore, 0.208mole of HC2H3O2 will also produce 0.208mole of CO2 
 
        
                    
             
        
        
        
Answer: four hundred and 18
Explanation:
Simple math showed that only 16 words are possible from a two-letter combination, but a three-letter code produces 64 words. Operating on the principle that the simplest solution is often correct, researchers assumed a three-letter code called a codon.
 
        
                    
             
        
        
        
When an electrolyte dissolves in water, the resulting solution conducts an electric current.
