Question

How many years would it take to spend avogadro number of rupees at rate of 10 lakh rupees per year

Answer 1

hey mate your answer is in attachment please check.


Avogadro's number = 6.023 x 10²³

If we spend Rs. 10,00,000 in 1 sec,

then Rs. 6.023 x 10²³ will be spent in  (6.023 x 10²³/ 10,00,000) =  6.023 x 1017sec. 

6.023 x 1017sec. = 6.023 x 1017 / (60x60x24x365) = 1.909 x 1010 years.

Answer 2

Here is the solution.

The time required is extremely large.

It is approximate 1.91 × 10^10 years.

Now, here's one interesting fact:

Current age of universe is 13.8 billion years.

And the time to required to spend all the money you have is 19.1 billion years !!!!

This means that even if you started spending money at the Big Bang itself, you wouldn't have finished by now.

That's the power of Avogadro Number !!
