It is estimated that there are 10^12 galaxies in the universe, each with about 10^12 stars. Each star has an average of 10^57 hydrogen atoms; using these estimates, the number of particles in the universe would be about 10^82.

What is the word used for the biggest number ever?

Googolplex. However it is useless to science because it exceeds the number of particles in the universe!


What is a relatively huge number?

One of the largest is called Graham's Number, which has so many digits that it can only be expressed as "powers of powers of powers". The last ten digits of Graham's number are ...2464195387. But the observable universe is too small to contain a written representation of the whole number, even if the digits were of subatomic size. It is many orders of magnitude greater than the number of elementary particles in the known universe.


What is 10 to the power of 100000000000?

(10)100,000,000,000 = a ' 1 ' followed by 100,000,000,000 zeros. I have no idea whether that number even has a name. It's of no use or interest to anyone except people who play with numbers. It's more than the total number of sub-atomic particles in the universe, and way more than the volume of the universe in cubic millimeters.


How are moles converted into number of particles?

The moles are converted into a number of particles by multiplying 6.02 by 10(with the power of 23)


How many particles in 1 gram?

In 1 gram of any substance, the number of particles can vary depending on the substance's molecular weight and Avogadro's number. To calculate the number of particles, you would first need to determine the molar mass of the substance in grams per mole. Then, you would use Avogadro's number, which is approximately 6.022 x 10^23 particles per mole, to find the number of particles in 1 gram of the substance.
