<u>Answer:</u> The number of moles of weak acid is
moles.
<u>Explanation:</u>
To calculate the moles of KOH, we use the equation:

We are given:
Volume of solution = 43.81 mL = 0.04381 L (Conversion factor: 1L = 1000 mL)
Molarity of the solution = 0.0969 moles/ L
Putting values in above equation, we get:

The chemical reaction of weak monoprotic acid and KOH follows the equation:

By Stoichiometry of the reaction:
1 mole of KOH reacts with 1 mole of weak monoprotic acid.
So,
of KOH will react with =
of weak monoprotic acid.
Hence, the number of moles of weak acid is
moles.
The units of ppm means parts per million. Also, It is equivalent to milligrams per liter. It is one way of expressing concentration of a substance. It u<span>sually used to describe the concentration of something in water or soil. We calculate the mass of CaCO3 as follows:
Mass = 75 mg/L (.050 L) = <span>3.75 mg CaCO3</span></span>
