Answer : Option B) Energy from the environment fuels production.
Explanation : Environmental fuels can be produced from lands and contribute towards production. The land can contribute for the production of a Biogas plant and help in generating energy from the plant. It uses mainly decaying matter and household wastes which are decomposed and then produce methane gas is then connected to the household kitchens.
 
        
                    
             
        
        
        
The concentration after dilution is 1.4%. 
We are aware that concentration and volume are related to each other by the formula - 
 
  =
 =  
  , where we have initial concentration and volume on Left Hand Side and final concentration and volume on Right Hand Side.
, where we have initial concentration and volume on Left Hand Side and final concentration and volume on Right Hand Side. 
Keep the values to calculate final concentration. 
 = (53.5 × 5.4)/205.0
 = (53.5 × 5.4)/205.0
Performing multiplication on Right and Side 
 = 288.9/205.0
 = 288.9/205.0
Performing division on Right Hand Side 
 = 1.4%
 = 1.4% 
Hence, the final concentration is 1.4%.

The complete question is - 
A 53.5 mL sample of an 5.4 % (m/v) KBr solution is diluted with water so that the final volume is 205.0 mL.
Calculate the final concentration and express your answer to two significant figures and include the appropriate units.
