5.224 g of water in a buret segment with a largest volume increment of 50.00 ml shows a corrected volume of 44.33 ml at a certain temperature. how many significant figures will be present in the correct representation of the density?

passing a magnet thought the

mixture , because iron gets attracted to magnet .

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

the correct answer to this question is 2

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.
