Calculate the mass of 10 mmol of vanillin and the theoretical yield of bromovanillin.

A. 152 mg, 173 mg
B. 173 mg, 152 mg
C. 150 mg, 175 mg
D. 175 mg, 150 mg

Answer :

Final answer:

The mass of 10 mmol of vanillin is calculated to be 152 mg. An accurate theoretical yield for bromovanillin cannot be determined without additional information about the reaction's stoichiometry and conditions. None of options is correct

Explanation:

To calculate the mass of 10 mmol (millimoles) of vanillin, we must first find the molar mass of vanillin. The molar mass of vanillin (C8H8O3) is 152.15 g/mol. Therefore, for 10 mmol, the mass is calculated as follows: Mass of vanillin = 10 mmol imes (152.15 g/mol) imes (1 mol/1000 mmol) = 1.5215 g or 1521.5 mg. the question asked for the mass in milligrams, the mass of 10 mmol of vanillin is 152 mg.

determine the theoretical yield of bromovanillin from vanillin, we would need additional information like the stoichiometry of the reaction and the conditions under which the reaction is taking place. Without such information, providing the theoretical yield is not possible. Thus, an accurate answer for the theoretical yield of bromovanillin cannot be provided with the given information. None of options is correct
