How many molecules are in 100. l of potassium hydroxide solution at stp?

Answer : There are in 100 Lof potassium hydroxide(KOH) solution at stp.

Explanation : To calculate the molecules we first need to find out the moles.

One mole of an ideal gas will occupy a volume of 22.4 liters at STP (Standard Temperature and Pressure, 0°C and one atmosphere pressure).

1 mole = 22.4 L

100 L =

100 L =

100 L = 4.46 mole potassium hydroxide(KOH)

Now , we need to convert 4.46 mole to molecules of KOH.

4.46 moles =

4.46 moles =

4.46 moles =

There are in 100 Lof potassium hydroxide(KOH) solution at STP.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

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.
