In part B of your reaction procedure, you are told to weigh your product, then add the equivalent weight of methanol. Calculate the amount of methanol that would need to be added (in milliliters) if your product weighed 2.31 g. Density of methanol = 0.791 g/mL
You will report a yield for your reaction in your post-lab. Methyl benzoate is the limiting reagent. Calculate the theoretical yield (in grams) for your reaction product assuming you use 0.40 mL of the limiting reagent. Hint: you will need to look up molecular weights/densities to complete this question.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
