How many protons in 20.02 moles of neon?

Answer 1

6.022x1023

Answer 2

The first step is to identify what you have and what you need. The units of our data is grams. The units that we desire is number of atoms. Therefor, to answer this question, we need two important tools of chemistry: the Periodic Table, where we can find the molar mass of the element (bottom of the element's box), and Avogadro's number, which is the number of atoms in one mole.

Going to our periodic table, we find the molar mass to be

M=20.1797 grams/mole

and Avogadro's number is

NA=6.022*1023 atoms/mole

To make the conversion, we simply track our units through the calculation:

80 grams of Ne * 1 mole Ne/20.1797 grams Ne * 6.022*1023 atoms Ne/mole Ne=

2.39*1024 atoms Ne

It is worth noting that any conversion factor can be reversed by reciprocating the value. In the above example, the molecular mass is given in grams per mole, which can be used to convert moles to grams. The reciprocal was used to convert grams into moles.

Answer 3

There are 10 protons per atom of neon. In 20.02 moles of neon there are 1.206 E25 atoms. This is determined by using Avogadro's number. So, there are 1.206 E26 protons in 20.02 moles of neon.

Answer 4

20.02 mol * 10 (molecular weight of neon) 8 Avagadro's # (6.022x10^23

= 1.205x10^26

Answer 5

There are approximately 1.21 x 10^25 protons in 20.02 moles of neon. This is calculated by multiplying Avogadro's number (6.022 x 10^23) by the number of moles of neon.

Answer 6

I do so believe it should be around 600.

Answer 7

The number of moles is 0,2.

Answer 8
