1. If air contains 78% N2. What is the solubility of N, in water at 25" & latm (KH 74.10 "mol/L)? 2. Calculate the mass percent of a solution containing 47.5 g of ethanol (CH.3CH,2OH) and 185ml of
LIO (Assume density of water = 1.0g/ml),​

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.
