How long would it take to count all the atoms in

In summary, if you could only count one atom per second, it would take approximately 2.3 trillion years to count all of the atoms in 12 grams of Carbon-12, based on Avogadro's number of 6.022 x 10^23 atoms per mole. This calculation takes into account the number of seconds in a year, which is 31,536,000.

Hint : How many grams of carbon 12 makes one mole? How many atoms is there in a mole?

hey, thanks a lot for your reply, yeah i know about Avagadro’s number but i am stuck on getting it into years, dividing it by how many seconds in a year?

It's easy to calculate the number of seconds in a year if you know the number of seconds in a minute, the number of minutes in an hour, the number of hours in a day and the number of days in a year.

1. How long would it take to count all the atoms in a single grain of sand?

It is estimated that there are approximately 7.5 x 10^18 atoms in a single grain of sand. If we were to count one atom per second, it would take approximately 238 trillion years to count all the atoms in a grain of sand.

2. How long would it take to count all the atoms in a human body?

The average human body is estimated to contain around 7 octillion atoms (7 followed by 27 zeros). If we were to count one atom per second, it would take approximately 2.2 quintillion years to count all the atoms in a human body.

3. How long would it take to count all the atoms in the Earth?

The Earth is estimated to contain around 1.33 x 10^50 atoms. If we were to count one atom per second, it would take approximately 4.2 x 10^42 years to count all the atoms on Earth.

4. How long would it take to count all the atoms in the Milky Way galaxy?

The Milky Way galaxy is estimated to contain around 100 billion stars, and each star is estimated to have around 10^57 atoms. This means that the Milky Way galaxy could potentially have around 10^67 atoms in total. If we were to count one atom per second, it would take approximately 10^59 years to count all the atoms in the Milky Way galaxy.

5. How long would it take to count all the atoms in the observable universe?

The observable universe is estimated to contain around 10^80 atoms. If we were to count one atom per second, it would take approximately 3 x 10^72 years to count all the atoms in the observable universe. This is significantly longer than the current age of the universe, which is estimated to be around 13.8 billion years.
