00.0 g of Ethyl Acetoacetate (MW 130.14) was fermented with yeast and sugar for 2 weeks. After workup we expected a simple reduction of a double bonded oxygen to an oxygen. How many moles of starting material? What is the new MW of the product formed?

When synthesizing benzoic acid, a student used 0.2 mol Bromo Benzene, 0.3 mol Mg and 0.25 mol CO2. Write out the general equations, check limiting reagent and indicate the maximum yield of benzoic acid in moles.
