Problem- The molecular weight of methyl benzoate is 136.16 g/mol and the molecular weight of the product is 181.15 g/mol. Assume you have excess acid and you start off with 2.8 g of methyl benzoate. What is the theoretical yield in grams of methyl-3-nitrobenzoate? Your final product weighs 2.0g. What is percent yield?
I am not able to get the correct answer please help me
