Number of moles = 5.7 moles of oxygen.
<u>Explanation:</u>
We have to convert number of molecules into number of moles by dividing the number of molecules by Avogadro's number.
Here number of molecules of oxygen given is 34.1 × 10²³ molecules.
Now we have to divide the number of molecules by Avogadro's number as,
Number of moles = 
= 
= 5.7 moles
So here molecules is converted into moles.
Answer:
The total pressure will be the sum of the partial pressure of these three gases.
Explanation:
According to Dalton law of partial pressure,
The total pressure exerted by mixture of gases is equal to the sum of partial pressure of the individual gas.
This expression can be written as,
P(total) = P₁ + P₂ + P₃ + ...... Pₙ
For example:
If the pressure of A is 2 atm and Partial pressure of B is 4 atm the total pressure will be,
P(total) = P₁ + P₂
P(total) = 2 atm + 4atm
P(total) = 6 atm
when third gas is added which exert the partial pressure of 4 atm,
Then total pressure will becomes,
P(total) = P₁ + P₂ + P₃
P(total) = 2 atm + 4atm + 4 atm
P(total) = 10 atm
Answer:
Explanation:
Hello,
Starting by the ideal gas law which always involves absolute temperatures:
At the initial given conditions, the moles are computed, assuming they are constant:
Now, by solving for the volume at the new pressure and temperature we get:
Best regards.
We have that the statement of Bohr's model understanding of electron energy levels is True
Option A
<h3>Electron energy levels</h3>
Generally, Bohr's model in his famous publication saw to explaining where <em>electrons</em> could be found. The model also explains the properties of different elements.
Therefore, The statement "A major advancement of from the Bohr model of the atom was the understanding of electron energy levels." is
True
