Question

How many moles are contained in 3.131x10^24 particles

Answer 1

Answer:- 5.199 moles.

Solution:- To do the conversion from number of particles to moles, we use Avogadro number. Given number of particles is divided by Avogadro number and we get the moles.

Avogadro number is $6.022*10^2^3$ . The calculations are given below:

$3.131*10^2^4particles(\frac{1mole}{6.022*10^2^3particles})$

= 5.199 moles

So, there would be 5.199 moles in $3.131*10^2^4$ particles.
