An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction. Also known as the electron acceptor, the oxidizing agent is normally in one of its higher possible oxidation states because it will gain electrons and be reducedExamples of oxidizing agents include halogens, potassium nitrate, and nitric acid. A reducing agent, or reductant, loses electrons and is oxidized in a chemical reaction. A reducing agent is typically in one of its lower possible oxidation states, and is known as the electron donor.

The atomic mass of Silver is 107.8682 by the periodic chart I have here. That means that 1 mole of Silver masses
107.8682 grams if the Silver is pure.
I mole of any element like silver is also 6.022 X 10^23 atoms of silver.
10^24 atoms is therefore more than a mole. You specified
2.3 x 10^24 atoms, so the number of moles will be
(2.3 X 10^24)divided by 6.022 X 10^23 = 3.819 moles
this number X 107.8682 grams/mole gives us 411.984 grams
Some laces get warm and some get cold
The concentration of hydrogen can be shown as:
[H+ ] = 3 * 10-5 M
pH can be determined as:
pH = - log [H+ ]
= - log (3 * 10-5)
= 4.53
Thus the pH of solution is 4.53
I believe you would just put a 2 in front of NH3 and keep the other ones as 1
