At a given temperature, the vapor pressure of heptane is 41.0 torr and the vapor pressure of octane is 21.0 torr. Assuming ideal behavior, what is the vapor pressure of a solution that contains three times as many moles of octane is heptane

the answer is the first option

explanation:

just googled it m8. not that hard

lol

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.
