The nonvolatile, nonelectrolyte chlorophyll, c55h72mgn4o5 (893.50 g/mol), is soluble in diethyl ether ch3ch2och2ch3. calculate the osmotic pressure generated when 12.9 grams of chlorophyll are dissolved in 226 ml of a diethyl ether solution at 298 k. the molarity of the solution is m. the osmotic pressure of the solution is atmospheres.

answer; talc and gypsum;

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.
