It is important because 1 plus one is 2 and 2 plus 2 is 4
Answer: Volume of water to be added is 116 ml.
Explanation:
Elevation in boiling point is given by:

= elevation in boiling point
i= vant hoff factor = 1 (for non electrolyte)
=boiling point constant = 
m= molality

Density of solvent =

(1kg=1000g)
Mass of solute (water) = x g


Density of solute =


Thus the volume of water to be added is 116 ml.
<span>No. A chemical reaction does not destroy matter but it can convert matter into another form or into a substance with a different molecular structure. Matter can even be converted into energy in a nuclear reaction.</span>
Explanation:
Nuclear fission : it a process in which large unstable nucleus splits into stable smaller stable nuclei. During this spilling large amount of energy is released.
The massive amounts of destructive energy is released during nuclear bomb explosion. The source of this energy, is the splitting of larger nucleus into smaller nuclei which releases large amount of energy.
