Question

1 mole paise ,l use 1 core paise per day then ,how much money I have save​

Answer 1

Solution

One mole of a substance has the Avogadro's number of particles

The Avogadro's number = 6.022 x 10^23

So the amount you won = 6.022 x 10^23

rupees

One year = 365 days

90 years = 365 x 90 x 24 = 788400 hours

1 hour has 3600 seconds

788400 hours = 788400 x 3600 =

2838240000 seconds

You spend 1 billion per second

You spend 1 billion per second

Amount spend = 2838240000 x 1,000,000,000

= 2.83824 x 10^18 rupees

Amount spend as a percentage =

(2.83824 x 10^18)/(6.022 x 10^23) x 100

= 4.71 x

10^-5 %

The percentage remaining = 100 -

4.71x10^-5
