Water has a density 1.0 g/cm3. what is the mass of 10.0 cm3 of water?

1.0g/cm3 means that the mass of one cm3 is 1.0gThe easiest method to use is the rule of three, and let x be the mass of 10.0 cm3 of water1g -- > 1.0 cm3x --> 10.0 cm3x= (10*1)/1x=10.0 gSo the mass of 10.0 cm3 of water is 10.0g

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.
