Write down the specific reaction under study. Find the melting point and boiling point of each reactant and product involved in the reaction (in Celsius °C). Use the “Handbook of chemistry and Physics” as a reference, you can find a copy of one in the school library, or you can just use the internet. Calculate the number of moles of salicylic acid. This is equal to the number of moles of acetyl salicylic acid. Determine the theoretical mass (grams) of...
