2,16·10²⁴ = 21,6·10²³
---------------------------
6,02·10²³ atoms ------ 1 mole of Ag
21,6·10²³ atoms ------ X
X = 21,6·10²³/<span>6,02·10²³
<u>X = 3,588</u> moles of silver

According to Dalton's law of partial pressure
The total pressure of a mixture of ideal gases is sum of the partial pressures of each gas present in the mixture
So if we know the partial pressure of all the gases we can determine the total pressure of the mxiture by adding all of them.
Thus
Ptotal = PCl2 + PF2 + PHe
Thus
Partial pressure of helium = 205 - ( 89 + 15) = 101 kPa
Answer:
Explanation:
This question appear incomplete because of the absence of options. However, places where silver recovery would happen in the United States are states where huge mining of copper, lead, zinc or gold are been mined. Examples of such places include Arizona, California and Oregon; where copper (and some other metals in some cases like gold in Oregon) is heavily mined and silver is recovered as a byproduct.
