Answer 2

Calculation of the Acid Formula

To determine the formula of the acid, we need to calculate the molar ratio between the acid and the base used in the neutralization reaction.

According to the given information, 4 grams of NaOH were used to neutralize the acid, and 9.6 grams of salt were formed as a result.

To calculate the molar ratio, we need to convert the masses of NaOH and the salt into moles. The molar mass of NaOH is approximately 40 g/mol, and the molar mass of the salt is unknown.

Let's calculate the number of moles of NaOH used:

Number of moles of NaOH = Mass of NaOH / Molar mass of NaOH

Number of moles of NaOH = 4 g / 40 g/mol = 0.1 mol Now, let's calculate the number of moles of the salt formed:

Number of moles of salt = Mass of salt / Molar mass of salt

Number of moles of salt = 9.6 g / Molar mass of salt

Since we don't have the molar mass of the salt, we cannot calculate the exact number of moles of the salt formed. Therefore, we cannot determine the molar ratio between the acid and the base.

Without the molar ratio, it is not possible to determine the formula of the acid. Additional information is needed to calculate the molar ratio and determine the acid's formula.
