Answer: There are 0.0129 moles of silver present in 1.4 grams of silver (Ag).
Explanation:
Given: Mass of silver = 1.4 g
Number of moles is the mass of substance divided by its molar mass.
As molar mass of silver is 107.86 g/mol. Therefore, moles of silver are calculated as follows.

Thus, we can conclude that there are 0.0129 moles of silver present in 1.4 grams of silver (Ag).
If the concentration of the hydrogen ions, increase then the solution would become more and more acidic and thus have a lower pH value than compared to the pH value before at the 1.0 X 10^-2 M.
