How do you determine the H3O concentration of a weak acid with a given pH?

pH is just the -log of the concentration of hydronium ion, and pOH is the same but for the concentration of hydroxide ion. The following equations are useful for solving this type of problem.
pH=-log[H30+]
pOH=14-pH
pOH=-log[OH-]
The inverse of log is 10^x, so [H3O+]=10^-pH

Is a solution of ph2 a weak acid?
Not necessarily. A solution that has a pH of 2 can have a low concentration of a strong acid or a relatively high concentration of a weak acid.
How does the concentration of acid differ from the strength of an acid?
An acid is termed weak or strong on the basis of it's disassociation constant (Ka). This is a function of it's chemical structure. Concentration is simply the number of molecules in a given volume.
Is the meaning of weak acid as same of that of dilute acid?
no, a dilute acid is any acid, strong or weak, that is in a low concentration. a weak acid ionizes to a small degree in water.
Is a weak acid similar to a dilute acid?
No. A weak acid is an acid that only partially dissociates in water. A dilute acid is a solution in which an acid, weak or strong, exists in a low concentration in water.
If you have a solution of a strong acid and a solution of a weak acid of equal concentration and volume then what happens?
The weak acid becomes in unionized form
What is a characteristic of weak acid?
A weak acid is not fully dissociated. You need to use the Ka to calculate the concentration of H+ for a specified concentration of the acid.

Can you have a high concentration of a weak acid?
An electrolyte is said to be concentrated, in a solution which has high concentration of ions. It is said to be dilute in a low concentration of ions solution. The electrolyte is strong, if a high proportion of the solute dissociates to form free ions. The electrolyte is weak, if most of the solute does not dissociate.

Can you know from its name if an acid or base is strong or weak?
It's not possible to determine whether an acid or base is either strong or weak. The only way is to see it's concentration. To determine whether the liquid is an acid or base is easy. An acid's chemical formula always has Hydrogen ions. Example HNO3 or HCl. Bases always have OH or Hydroxide. Example NaOH2.
If 1.0L of this buffer contains an acid concentration of 0.50M and a conjugate base concentration of 0.50M what is the buffer pH?
When the concentration of the weak acid is the same as the concentration of the conjugate base, the pH will be equal to the pKa of the weak acid. This is because from the Henderson Hasselbalch eq:pH = pKa + log [acid]/[conj.base] and when [acid] = [conj.base], the log of 1 = 0 and pH = pKa.
Do strong acids have higher concentrations than weak acids?
No. The concentration of and acid and the strength of an acid are two unrelated values. The strength of an acid is the degree to which it will break apart into ions when dissolved in water. It is an inherent property of any given acid. The concentration of an acid is how much of it is present in proportion to its solvent (usually water) and is independent of any properties of the acid itself. You can take a solution of some acid and add it to water to lower the concentration or boil off some water to raise the concentration, but the properties of the acid itself remain the same.
What makes an acid or base weak?
H+ion concentration in the solutions
