    There is 0.25 grams of C11H12O3 produced

    Explanation:

    Step1: Data given

    vanillin = C8H8O3

    Mass of vanillin = 0.2 grams

    Molar mass of vanillin = 152.15 g/mol

    Acetone = 58.08 g/mol

    Step 2: The balanced equation

    C8H8O3 + C3H6O → H2O + C11H12O3

    Step 3: Calculate moles of C8H8O3

    Moles C8H8O3 = mass / molar mass

    Moles C8H8O3 = 0.2 grams / 152.15 g/mol

    Moles C8H8O3 = 0.0013 moles

    Step 4: Calculate moles of C11H12O3

    For 1 mol vanillin we need 1 mol acetone to produce 1 mol C11H12O3

    Step 5: Calculate mass of C11H12O3

    Mass C11H12O3 = moles * molar mass

    Mass C11H12O3 = 0.0013 moles * 192.21 g/mol

    Mass C11H12O3 = 0.25 grams

    There is 0.25 grams of C11H12O3 produced
