If the concentration of glucose is increased from 0.1 m to 2.0 m, will the conductance change? why?

             No, the conductance will not change.

                    Conduction is defined as the transfer of energy in the form of heat or electric charge through any given substance. Electric charge is the movement of electrons from high potential to lower potential. Hence, we can say that electrons can travel through either a metallic substance (having sea of free electrons) or Ionic compounds (having +ve and -ve ions).

                     In given statement, Sugar (Glucose; C₆H₁₂O₆) is a covalent compound. It neither has free electrons in it structure nor it is an ionic compound to produce ions. Hence, due to absence of both it will not conduct electricity in solution form either its concentration is kept high or kept low.

i think its 5049.

i hope this !

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
