If one has a solution of 0.10 m silver nitrate and it is diluted by a factor of two, what is the new concentration

The new concentration would 0.05 M

Dilution factors are the number of times a solution is diluted such that the volume is multiplied each time.

Thus, multiplying the volume of a solution means that the concentration is divided each time.

For example, a solution that is diluted by a factor of two means that the volume is multiplied by two. When this happens, the concentration would be divided by two.

Thus, for a 0.1 M solution diluted by a factor of 2, the new concentration would be:

                   0.1/2 = 0.05 M

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.
