Answer:
<h2>12.82 moles </h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have

We have the final answer as
<h3>12.82 moles</h3>
Hope this helps you
The Best Answer: 1 - (.47+.23) = 0.30
If Ne has a mole fraction of 0.47 (or 47/100) and Ar is 0.23, then H2(or He) has a mole fraction of 0.30
This means the gas mixture is 30/100 H2(or He).
7.85 x 0.30 = 2.355 atm
That would be phosphorus. It’s electron configuration is 1s^2 2s^2 2p^6 3s^2 3p^3
Answer:
The answer to your question is Magnesium Perchlorate
Explanation:
IUPAC Rules to name ternary salts of chlorine
1.- Ternary salts use prefixes and suffixes it depends on the number of oxygens they have.
Example
Metal + Chlorine + 1 oxygen = Name of the metal + hipo chlor + ite
Metal + Chlorine + 2 oxygens = Name of the metal + chlor + ite
Metal + Chlorine + 3 oxygens = Name of the metal + chlor + ate
Metal + Chlorine + 4 oxygens = Name of the metal + per + chlor + ate
For this compound the name is Magnesium Perchlorate.
