The product of prime polynomials is equivalent to 36x3 – 15x2 – 6x is letter B which is 3x(3x – 2)(4x 1). Below is the solution. 
3x(3x - 2) (4x + 1)
= 9x2 - 6x (4x + 1)
= 36x3 + 9x2 + -  24x2 - 6x
= 36x3 - 15x2 - 6x
       
        
                    
             
        
        
        
Answer: The value of  for chloroform is
 for chloroform is  when 0.793 moles of solute in 0.758 kg changes the boiling point by 3.80 °C.
 when 0.793 moles of solute in 0.758 kg changes the boiling point by 3.80 °C.
Explanation:
Given: Moles of solute = 0.793 mol
Mass of solvent = 0.758

As molality is the number of moles of solute present in kg of solvent. Hence, molality of given solution is calculated as follows.

Now, the values of  is calculated as follows.
 is calculated as follows.

where,
i = Van't Hoff factor = 1 (for chloroform)
m = molality
 = molal boiling point elevation constant
 = molal boiling point elevation constant
Substitute the values into above formula as follows.

Thus, we can conclude that the value of  for chloroform is
 for chloroform is  when 0.793 moles of solute in 0.758 kg changes the boiling point by 3.80 °C.
 when 0.793 moles of solute in 0.758 kg changes the boiling point by 3.80 °C.

The observation in the illustration remains in accordance with the law of conservation of mass assuming that moisture is present in the container.
<h3>What is the law of conservation of mass?</h3>
The law state that mass can neither be created nor destroyed. However, mass can be converted from one form to another.
In this case, the ion was placed in a container of pure oxygen. Assuming that moisture is present, iron reacts with oxygen to form rust according to the following equation:

The rust formed will weigh more than the initial weight of the iron. 
Without the presence of moisture, one can effectively conclude that the observation violates the law of conservation of mass.
