NaOH is treated with an organic acid.

Normality=0.2N
Volume= 45.7 cubic centimeter
mass of organic acid= 0.22
give name and strutural formula of the acid

To determine the name and structural formula of the organic acid, we need to follow a few steps.

Step 1: Calculate the number of moles of NaOH used.
To find the number of moles of NaOH, we can use the equation:
moles = normality * volume
Substituting the given values:
moles of NaOH = 0.2 N * 45.7 cc
moles of NaOH = 9.14 millimoles (mmol)

Step 2: Determine the number of moles of the organic acid.
Since NaOH is a strong base, it will react with the acid in a 1:1 stoichiometric ratio.
Therefore, the number of moles of the organic acid is also 9.14 mmol.

Step 3: Calculate the molar mass of the organic acid.
The molar mass can be calculated by dividing the mass of the organic acid by the number of moles:
molar mass = mass / moles
molar mass = 0.22 g / 9.14 mmol
molar mass = 24.07 g/mol

Step 4: Identify the name and structural formula of the acid.
To determine the name and structural formula, we need more information about the organic acid. The molar mass alone is not sufficient to identify a specific compound. However, based on the given information, the name and structural formula of the acid cannot be determined without additional data or context.
