# Question #09dee

##### 1 Answer

If the Molarity concentration of an acid is

The Molarity is the Concentration [ ]. While your question does not distinguish which concentration is represented I will assume for our purposes the the

Therefore,

To convert a Molarity concentration to pH we can calculate

Therefore,

Now, pH + pOH = 14, so pOH = 14 - pH

Therefore,

Then we can convert the

Moving the decimal gives us a value of

Therefore

Some checkpoints to see if your calculations are correct.

The exponents of the concentrations should add up to -15.

-12 and -3 give us a value of -15

The pH should value of the pH and pOH should be less than the exponents of the concentrations.

pH = 11.27 < 12

pOH = 2.73 < 3
