Question

Calculate and record the experimental benzoic acid molar mass. The molar mass of benzoic acid is calculated as grams of benzoic acid divided by moles of benzoic acid. Given: Mass of Benzoic Acid = 0.4g.

a. 53.1 g/mol
b. 65.4 g/mol
c. 89.1 g/mol
d. 110.2 g/mol

Answer 1

The molar mass of benzoic acid cannot be calculated with the given information.

Step-by-step explanation:

The molar mass of benzoic acid can be calculated by dividing the mass of benzoic acid by the number of moles of benzoic acid. In this case, the given mass of benzoic acid is 0.4g. To find the molar mass, we divide this mass by the moles of benzoic acid.

Molar Mass = Mass of Benzoic Acid / Moles of Benzoic Acid

Moles of Benzoic Acid = Mass of Benzoic Acid / Molar Mass of Benzoic Acid

Substituting the given values, we get:

Moles of Benzoic Acid = 0.4g / X

Since we don't know the molar mass of benzoic acid, we can't determine the moles of benzoic acid or the experimental molar mass. Therefore, we can't calculate and record the experimental molar mass of benzoic acid with the given information.
