Part 1 You need to find the empirical formula of a compound. This compound has 53.3 g of O, 48.38 g of C and the tiny amount of 8.12 g of H.

Part 2

Based on the empirical formula you found above, what is the molecular formula if the molar mass of the whole compound is 180.15 grams per mole?

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.
