Fascinating Facts

The entire Karnataka State may be submerged to a depth of much more than 100 kilometers.
You can calculate and check
Consider 20 drops as 1Cm³
Find the volume of Avogadro number of drops. This volume will be in Cm³
Convert the volume into Km^3.
Divide it by the area in Km². The answer will be the height in Km.
Your life time will not be sufficient to distribute that wealth. In fact it will take thousands of years.
Again you can calculate and check.
Number of people x 1000 x 60 x 60 x 24 x 365 . This will be the amount you will spend in a year.
Find how many years you will need to spend Avogadro number of Ruppees.
Spending one billion a second it would take 19 million years.

Avogadro number(N) is defined as the number of Carbon-12 atoms in 12g of C-12.
Avogadro number of particles(N) is considered as 1 mole of particles. Thus Avogadro number of methane molecules(N) will be one mole of methane. 16g of methane (molecular weight of methane is 16)will contain N molecules of methane, they will occupy 22.4 liters under standard conditions.
Thus one mole of any gas under standard conditons will occupy 22.4 liters. This is called "gram molecular volume".
The precise number is unknown, since it is not possible to physically count the number of atoms.
It is normally considered as 6.023 x10²³
More accurately 6.0221415 x 10²³ (with an uncertainty of 0.000 0010 x 10²³)
There are many ways available for estimation of this number, the most accurate for the present being through X-ray studies of crystals.
A number of web sites are available which give information about these methods and other fascinating details. Just browse for Avogadro number.
