The far more common hydrogen isotope, protium, has NO neutrons in the nucleus.
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
. The calculations are given below:
![3.131*10^2^4particles(\frac{1mole}{6.022*10^2^3particles})](https://tex.z-dn.net/?f=3.131%2A10%5E2%5E4particles%28%5Cfrac%7B1mole%7D%7B6.022%2A10%5E2%5E3particles%7D%29)
= 5.199 moles
So, there would be 5.199 moles in
particles.
The danger from radon gas would most likely be greatest in well-insulated homes. It is a toxic gas.
<h3>What is radon gas?</h3>
Radon is a naturally radioactive gas generated from different elements such as uranium or radium.
Radon is generated when these radioactive materials naturally decompose in the soils and/or rocks.
Radon is highly toxic and therefore this gas must be avoided to maintain healthy conditions in a home.
