Answer:
107.8682 u
Explanation:
Well Silver has an atomic mass of aproximately 107.9. 1 mole of silver atoms = 107.9g and there are 6.02x10^23 atoms in one mole. Therefore to find mass of one atom you should divide the mass by Avodgadro's constant to find the mass of one atom because they all have an even distribution of mass.
The average atomic mass of the element takes the variations of the number of neutrons into account, and tells you the average mass per atom in a typical sample of that element. For example, the element silver (Ag) has two naturally occurring isotopes: Ag-107 and Ag-109 (or 107Ag and 109Ag).
Answer:
(C) knowing which minerals are in a rock can help you identify and classify that rock.
Explanation:
It is the truth.
The pH of a buffer solution with acid that (PKA 6. 1) is exactly half as concentrated as its conjugate base is 6.4.
<h3>What is a buffer solution?</h3>
A buffer solution is a solution that has a maintained pH, not basic or not acidic. Its pH changes when acid or base is added to the solution.
We had to figure out the acid's concentration, which is exactly half that of its potential base.
We know that pH = pH_log
We have less than 6.1 pH so this is a conjugated base.
This will equal to 6.1 + log2 = 6.4
Thus, the pH of a buffer solution with acid is 6.4.

The polar heads interact with water, the nonpolar tails do not. A double- stranded DNA molecule that contains 30% guanine.
are referred to as hydrophobic, face the interior of the bilayer, where they are shielded from water. On the other hand, the polar regions of the molecules, termed hydrophilic, face outward where they interact with the water inside and outside of the cell.
A substance with at least one hydrogen atom that can dissociate to form an anion and an H+ ion (a proton) in aqueous solution, thereby foming an acidic solution.
A substance that produces one or more hydroxide ions (OH−) and a cation when dissolved in aqueous solution, thereby forming a basic solution.
