Hello!
To solve this question, we need to use the
Avogadro's Number, which is a constant first discovered by
Amadeo Avogadro, an Italian scientist. He discovered that in a mole of a substance, there are
6,02*10²³ molecules. Using this relationship, we apply the following conversion factor:
![8,50* 10^{24}molecules* \frac{1 mol Na_2SO_3}{6,02* 10^{23}molecules}=14,12 molesNa_2SO_3](https://tex.z-dn.net/?f=8%2C50%2A%2010%5E%7B24%7Dmolecules%2A%20%5Cfrac%7B1%20mol%20Na_2SO_3%7D%7B6%2C02%2A%2010%5E%7B23%7Dmolecules%7D%3D14%2C12%20molesNa_2SO_3%20%20%20)
So, 8,50 * 10²⁴ molecules of Na₂SO₃ represent
14,12 moles of Na₂SO₃
Have a nice day!

Because your smell sence is stronger than the others
Explanation:
I think the answer would be C. They are unreactive.
Answer:54.82%
Explanation:
Percentage of carbon = mass of carbon in that compound/ mass of the compund *100
216/394*100 = 54.82%
